Stephen Colbert closed out his weeklong trip to Philadelphia by having both Democratic presidential candidates guest on the same show Thursday night. Sen. Hillary Clinton appeared first, attempting humor on how she can fix anything as well as take phone calls at 3 a.m. This, still? Really? Enough already.

Clinton fixed the screen, which ultimately allowed Sen. Barack Obama to appear later in the show by satellite. Proving once again that Clinton is her own worst enemy in this campaign. And that Obama will take the higher road.

After the jump, former Sen. John Edwards also delivered the Word. Edwards. Who’s he, again?
