• "Pope Benedict is quitting. That's a tall hat to fill." -- David Letterman
• "The Pope will be replaced, of course. When one Pope goes, another one popes up in his place." -- Craig Ferguson
• "They're going to miss Pope Benedict. He's very underrated. This is the guy who wanted to replace Communion wafers with unlimited bread sticks." -- David Letterman
• "The Vatican said that as soon as the Pope resigns, he will no longer be infallible. The Vatican said it's the same thing that happened to Oprah." -- Conan O'Brien
• "The Vatican was struck by lightning after the Pope announced he was retiring. That really happened. Sounds like someone's not handling the breakup well." -- Conan O'Brien
• "Pope Benedict says he is resigning because of physical problems. Apparently it's an old football injury from throwing all those Hail Marys." -- Jay Leno
• "The Pope said that at age 85 he cannot physically go on. Meanwhile, Hugh Hefner is going to be 87, and he just married a 26-year-old. So much for that celibate lifestyle!" -- Jay Leno
• "We're learning more about the Pope's condition. The Vatican announced that Pope Benedict hit his head during his March 2012 trip to Mexico. In fact, right after that, the Pope said he's sworn off spring break forever." -- Jay Leno
v "With the Pope retiring, more than 100 cardinals will sequester themselves in the Sistine Chapel to choose the next Pope. They'll send out white smoke if they've chosen somebody, black smoke if they haven't chosen somebody and a text message when they find out that it's 2013." -- Jimmy Fallon
• "Actually, when the voting's done, the cardinals burn their ballots. People wait outside the Sistine Chapel to see what color the smoke is. If it's white smoke, they've agreed on a Pope. If it's black smoke, no decision's been made. If it's green smoke, Willie Nelson has somehow gotten into the Sistine Chapel." -- Craig Ferguson

Peter was telling a friend that he had just lost his job.
"Why did the foreman fire you?" the friend asked in surprise.
"Oh," Peter said, "you know how foremen are. They stand around with their hands in their pockets watching everybody else work."
"We all know that," replied his friend. "But why did he let you go?"
Jealousy," answered Peter. "All the other workers thought I was the foreman."
