[Jimbuna]

Three men are all working on building a house. They go up to the roof for lunch, and unwrapped their sandwiches. The Brunette says "if I get one more Tuna sandwich, I'm going to jump off this roof and kill myself. The black haired one says "if I get one more pickle and lettuce sandwich, I, too, am going to jump off this roof and kill myself. The blonde looks at his sandwich and also declares, "if I get one more peanut butter and jelly sandwich, I'm going to jump off this roof and kill myself."
The next day, they all get the same sandwiches and kill themselves. That night, their wives all meet up and mourn. "If I had known that my husband was going to kill himself over a sandwich, I wouldn't have given it to him." The brunette cries. "Same," the raven head replies. They both look at the blonde. "Don't look at me, he packed his own lunch!"
