There were three guys waiting for a bus on a bench when the first guy farts, ‘WHOOOOOSSSSSHHH..’

No one minded it. Then second guy farts, ‘WHOOOSSSHHHHH..’

Again no one thouhgt anything of it until the third guy let one, ‘PPPPPPUUUUUHHHHHH..’

The firSt two guys then looked at the third guy and simultaneously said, ‘STRAIGHT!’
