Better add this to the ultimate wake up prank compilation.
One sleeping audience member was in for an surprise when several dancing half-naked men woke her up during "The Great Improvisation Show" in the Netherlands.
The woman appeared to be sleeping heavily as performers tried several times to rouse her without success. But the sleeping woman eventually awoke -- only after the men stripped off their shirts and surrounded her.
That'll teach her not to fall asleep during an improv show.
