On last night's Tonight Show, Jay Leno announced his, um, "decision" to retire in 2009 and pass the torch to Conan O'Brien. In explaining his, um, "decision," he recalled the messy situation in the early '90s when NBC passed over David Letterman for the Tonight Show job in favor of Leno prompting Letterman to bolt to CBS. "A lot of friendships were permanently damaged," he said. "Quite frankly, I don't want to see anybody go through that again."
