The 3 paddy's are working on a building site and it's lunchtime again.
Paddy the Englishman opens his sandwiches and says "not cheese again"
Paddy the Scotsman opens his sarnies and says " not bloody ham again"
Paddy the Irishman opens his sandwiches and says "not tuna again"
After a short discussion each of them agree that if they get the same sandwiches the following day they're all going to chuck themselves off the roof of the building site.
Sure the next day arrives and the horn blows for lunchbreak again.
Paddy the Englishman opens his lunchbox and it's cheese again. Says his goodbyes and takes a dive off the 10 storie building to his death.
Paddy the Scotsman opens his piece and once again it's ham. Says goodbye to paddy the Irishman and jumps off the building, stone dead.
Paddy the Irishman opens his sarnies and it's tuna once again. Throws the sandwiches to the ground and walks off the edge of the 10th floor to his death.
At the funerals the 3 sobbing wives discuss the deaths amongst themselves.
Paddy the Englishman's wife "I never knew Paddy didn't like cheese, it's such a shame"
Paddy the Scotsman's wife "I didn't know my Paddy didn't like ham, the kids and I will miss him so much"
Paddy the Irishman's wife looks bewildered through her tears and says "My Paddy made his own sandwiches"
