Paddy, Jock and Bob are three builders working on a multi-story car park. Every day at lunchtime they go up to the top floor for the view whilst they eat their packed lunches.
One day, upon opening his lunchbox, Bob goes really quiet and then shouts
"Cheese and pickle! AGAIN! Every BLOODY DAY!! I am SICK OF CHEESE AND BLOODY PICKLE!! If my wife puts this crap in my sarnies again I will kill myself.
The other two look at him, shocked, their jaws agape.
Bob continues "I tell you lads, I've had enough. If I've got cheese and pickle again tomorrow I'm gonna throw myself of this building and end it all."
A hush descends upon the three men as Jock opens his lunchbox.
He looks disgusted. "Ah Shite, it's haggis. Ah fuppin HATE HAGGIS!! EVERY FUPPIN DAY THE SAME SHITE" AH CANNAE TAKE NO MORE HAGGIS!!"
He puts the haggis down and says "I'm with you Bob. If ma missus packs me haggis one mooor time ahm throwin meself off right behind ya mate".
Paddy looks on, hardly daring to open his lunchbox. After a few moments he does, and looks at the others in dismay.
"Ah right", says Paddy. "Tuna Mayo. I can't stand the stuff, in fact OI FECKIN HATE TUNA MAYO!! FECKIN STUFF GETS EVERYWHERE!!" SHOITE!
He continues "Oim with you two fells so I am. If I open my lunchbox tomorra and its tuna feckin mayo, I'm comin witcha, I'll top meself too!"
The three men decide to write a solemn oath, and each signs it before putting it under the pile of pallets they use as a seat.
The rest of the day passes in silence....
Next day, one o'clock, the three men make their way up to the fifteenth floor as usual, and take their seats on the pile of pallets.
Bob opens his lunchbox. He pauses, closes it again slowly, and without saying a word he walks to the edge and dives off. There is a horrible crunch and Jock & Paddy look at each other, tears in their eyes.
"Well Paddy", says Jock. "A vow is a vow me old son." He slowly opens his lunchbox, to reveal a thick slice of haggis.
"Goodbye Paddy, it was nice knowin ya." Jock then puts down his lunchbox and runs full pelt off the edge of the building. Again there is a gruesome scream followed by a sickening thud from below.
Paddy sits there, alone and distraught. He pauses for a while, but then opens his lunchbox slowly.
"Oh bejesus. Tuna mayo. Oh no, please no!"
"Well I'll not be lettin the other fellas down now, a vow is a vow after all"
And with that he shuffles off the side of the building and falls to his death.
Two weeks later, at the joint funeral of Bob, Jock and Paddy, their wives comfort each other and weep uncontrollably.
Bob's wife says "I just don't understand it. He never told me he hated cheese and pickle. If I'd only known I would've given him something else"
Jock's wife says "Aye, my Jock never said a word about hatin' haggis, I thought he loved the stuff, so I gave it him every day, I wish he'd said somethin', I had no clue."
Paddy's wife says "Well it's really confusin' for me, cos my Paddy used to make his OWN sandwiches."
