These three guys (English, Scottish, Irish) sneak into a farmers field and start grabbing the crops.
The farmer soon catches them and puts them against the wall with his shotgun. He says "Shove 50 of yer favourite fruit up yer ass to live. You die if you laugh."
The English guy chooses grapes.
He manages 23 before laughing, and gets blown away by the farmer.
He goes to heaven and saint Peter asks why he's laughing, he doesn't answer.
Back in the field, the Scottish guy picks cherries.
He gets to 29 before laughing, and gets viciously slaughtered by the farmer in a blood bath.
When he too pops up in heaven, St Peter askes him why he was laughing.
He said, "the Irish guy chose pineapples!"
