An Australian, an American, and an Irish builder...

...are sitting on top of the (unfinished) 18th floor of the building they've been working on, eating their lunches.

The Australian man pulls out a vegemite sandwich, and he says to the other two, "If i get another vegemite sandwich tomorrow, I'm going to jump off this building. I'm sick of this vegemite."

The American man next to him, with a horrified look on his face, pulls out a hotdog. He says, "I agree. If I get another hotdog tomorrow, I will jump off this building with you. I've had enough."

The Irishman pulls out an Irish stew. "Ugh, Irish stew again. Yep, if I get this tomorrow, I'll jump with the two of you."

So the next day they're all sitting in the same spot, and they all pull out the same lunches as before. Grimacing, they jump off the building and plunge to their deaths. They end up having a joint funeral, because they were good friends.

At the funeral, all three wives are sitting next to eachother, discussing their husbands.

The Australian woman says to the other two, "I'm so upset. If only he had've TOLD me he didn't like vegemite, I would've given my husband something else."

The American woman says, "I agree, I just wish my husband had've spoken to me about it, then he would still be here."

They both turn to the Irish woman, who then says, "Don't look at me, Paddy makes his own lunch,"
