Confirming long-held suspicions, a 10-year study has found that falling asleep in tank tops results in at least one titty popping out.

“We can now conclusively say that it’s impossible for both titties to be contained while sleeping in tank tops,” said lead researcher Claire Ledum.

“After studying factors such as the type of tank top, bra usage, duration of sleep, and the size of the titties in question, we’ve concluded that it’s impossible to sleep in tank tops without this phenomenon occurring,” added Ledum.

“We have found similar results among women as well as some men with ‘moobs.’”

Research concluded that falling asleep in a tank top is comparable to sleeping without any shirt at all.
