Two guys meet in heaven, and are chatting about how they died. The first guy says he froze to death, and the second guy says he died of a heart attack.
"How did that happen?" asks the first guy.
"Well, I came home and thought I heard my wife and another man. But when I went inside, I searched and searched for her, but couldn't find anybody. I was stricken with such remorse for accusing my wife of infidelity that I had a heart attack on the spot."
"Geez," says the first guy. "If you'd've opened the fridge, we'd both be alive right now."
