There was a Mexican, a Asian and a Pakistani man working on the top of a tall building.
The Mexican said, "If my wife makes me tacos tomorrow for my lunch, I'll jump off this building."
The Asian said, "If my wife makes me rice tomorrow, for my lunch, I'll jump off the building."
The Pakistani said, "If I have curry tomorrow, I'll jump off the building."
The next day, the Mexican had tacos, the Asian had Rice, and the Pakistani had curry. So they all jumped.
At the funerals, the wives of the Mexican and Asian said, "Why didn't they just tell us they didn't like their lunches?"
The wife of the Pakistani said, "I don't know why my husband jumped off the cliff. He made his own lunch."
ALTERNATIVE PUNCHLINE
The wife of the Mormon said, "I don't know why my husband jumped, as he has several wives and I have no idea what sister wife Julie made him for lunch, nor was I aware he worked on a tall building. I thought he was an accountant."
Obviously to use this alternative punchline you need to modify the whole joke.
I will leave that up to you.
My work here, is done.
