A roundup of the late-night comics.
Bill Maher: I love the springtime. It's a time of renewal, when the old U.S. attorneys are plowed under.
Jay Leno: Kind of ironic. While testifying, Al Gore was questioned by Hillary Clinton. Kind of global warming meets global cooling. I'm surprised it didn't start to rain right there.
Leno: Oh, I love when they say this, this thing with the attorneys is a constitutional crisis. Oh, please. We haven't used the Constitution for years.
Jimmy Kimmel: Al Gore spoke on Capitol Hill today to urge lawmakers to do more to fight global warming. … He didn't limit his thoughts to the environment though. He also spoke very passionately on the subject of child care.
[Graphic: "Al Gore's Parenting Tip of the Day"] Al Gore: If the crib's on fire, you don't speculate that the baby is flame-retardant.
Jimmy Kimmel: Really, just good common sense.
David Letterman: Fourth anniversary of the start of the war. Yep, a lot of protests, a lot of anti-war protests. And the Bush administration said they were surprised by the number of protests. And I was thinking: "You know what? I'm not surprised they were surprised." That seems to make sense.
Conan O'Brien: This is interesting. According to a new report by a genealogy company, Barack Obama's great-great-great-grandfather was born in Ireland. Yeah. Yeah, that should really solidify Obama's support among Irish African-Americans raised in Hawaii.
