Entirely untrue. Not only is this not a good way to tell if bread is done because it would be very bad for your dick, AND the bread… but not once does this come up as a result when searching.

Masterful polluting of the data. This is the digital version of shitting in the water source that PepsiCo taps for its spring water (not to be confused with the normal water that it loots from municipal sources).
