A horse walks into a bar and asks "Are you hiring?"

The bartender looks up and down the horse and says "No, not at the moment. Perhaps you'll have more luck asking at the circus?"

The horse says "Why would the circus need a bartender?"

Saw this on Reddit ages ago, and it still cracks me up:

So there's a farm. On this farm, there's a cow, a chicken, and a horse, and the three of them are best friends.

They do just about everything together. And one day, they're sitting at the window of the house, and the farmer's kid is watching MTV, and they're watching it, and they hear the music, and the horse says "you know what? I'm gonna learn how to do that."

So the horse calls up Guitar Center, and he says to the guy on the phone, "Hey, listen. I wanna learn to play guitar."

Guy on the phone says "no problem. Come on down."

"No, there might be one problem. I'm a horse."

"Naw, it ain't a problem. We'll get some attachments, I can teach you to play. Promise."

So horse turns out to be a natural. He gets GOOD. And he calls over Cow and Chicken and he's like "LOOK WHAT I CAN DO" and he jams out like Jimi Hendrix. And Cow says "holy shit. That's awesome. I want to learn to do something like that too. What's like that?" And horse says "Bass. Learn to play bass."

So Cow calls up Guitar Center, and she says "Hey, listen, I wanna learn to play bass guitar."

Guy on the phone says "No problem, miss, come on down."

"Eh, this might be a problem. I'm a cow."

"Nah, no problem. I helped a horse recently, I can teach you to play too. Promise."

So Cow learns to play the bass, and Cow is fucking amazing at it. So Cow and Horse are jamming, and Chicken gets a bit jealous. He says "Damn, I wanna learn something too. But not like that."

Horse says "Well, I mean, we need a drummer around here."

So Chicken calls up Guitar Center, and he says "Hey, listen, I wanna learn to play drums."

Guy on the phone says "No problem, man. Come on down."

"Eh, maybe a problem. I'm a chicken."

"Naw. Ain't no thing. I taught a horse guitar and a cow bass. I can teach you drums."

So chicken learns the drums, and he's fucking amazing. So Cow, Horse, and Chicken all start having jam sessions whenever the farmer's out. And one day they're playing, and a big record agent is driving down the road. And he hears them, and he's like "what the fuck? that sounds amazing." so he stops at the farm, and he finds them all playing in the barn. And he says "Holy shit. You guys sound AWESOME. I wanna represent you, make this a real band, make some music. You're gonna be HUGE."

So Cow and Chicken and Horse take this guy's deal, and they move to the city, they cut albums, and they're big. REAL big. Top 10 hits, platinum albums, the works. They get set for their first tour. But there's a problem, see. Horse gets a phone call, his mom's real sick. Cow and Chicken, though, they're cool as hell. They say "Listen. Go see your mom. We'll delay the first show a couple of days, so fly back home, spend some time with her, and then jump on a plane and come meet us."

Horse says "Thanks, guys. you're the best," and he takes off.

Couple of days later, Horse's mom is just fine. Turned out to be a real bad cold, she gets over it, and he spends another night there. The following morning, he gets a call. It's his agent. Cow and Chicken's plane went down, they died in the crash. The band is done. he's lost his best friends. And horse, this breaks him, man. He's been through so much with them, and he feels real down in the dumps. So he takes a walk, and while he's on that walk, he just can't shake the blue, so he figures to himself "Alright, alright. One drink, just to get over it."

So Horse walks into the local bar. Bartender looks at him and says "Hey. Why the long face?"

"Are you two datin? "

Just horsing around.

Why did the Shetland go to the doctor?

Because he was a little horse.

The caption reads "You look like me before I got braces!" but you can't tell which one is talking.

"...and then he put two hands in and I told him to clap. He said he couldn't. Then I said, 'Pretty tight, huh?'"

She told him, her boyfriends "horse" size

"And so I said 'if it weren't for my horse, I wouldn't have spent that year in college' and this eavesdroppin' motherfucker just lost his fuckin' mind!"

They're singing AC\DC's Thunderstruck...
Girl: Thunder!
Horse: Hrr hrrr hr hrrHrrrrrr

That's your penis? And you wanna date her? With that?
