A guy was at the supermarket and after buying a few items he began to line up in a really long queue for the checkout. After about 15 minutes stood in line he reached the checkout girl, and just at that moment he realised he needed some condoms. Not wanting to queue up again, he said to the girl, 'Oh, I meant to buy some condoms, but forgot.'
'Do you know what size you are?' she asked.
'No,' he replied.
'OK, drop your pants and I'll tell you what size you are.'
The man not being the shy type, dropped his trousers and the girl had a feel with her hand, and said into the microphone, 'One pack of large condoms to aisle three please.' So the man pulled up his trousers, the condoms are brought to him, he paid his bill and left.
Another male customer sees this and thinks he would like the checkout girl to fondle him, so her told her the same excuse. A similar course of events take place, only this time after a good feel, she says over the tannoy system, 'One pack of medium size condoms to aisle three please.' The condoms are brought to him, he pays his bill and goes on his way.
Also watching this course of events was a rather exciteable 15 year old boy, who then decides to queue up and try the same routine. 'I'd like to buy some condoms please, but I forgot them,' he said.
'Do you know what size you are? she asked.
'No,' he replied.
'OK, I'll check. Whoops, oh dear. Mop and bucket to aisle three please!'
