Two guys show up in Heaven at the same time. The first guy says he froze to death, and the second guy tells him that he died of a heart attack....

"How did that happen?" asks the first guy. "Well, I came home and thought I heard my wife with another man. But when I searched the house, I couldn't find anybody. I was so stricken with remorse for wrongly accusing my wife of infidelity, I had a heart attack and died on the spot."

"Geez," says the first guy. "If you'd opened the fridge, we'd both be alive right now."
