Last night, David Letterman's monologue was hijacked by a rambling purple woman in a parody of the moment that was apparently the highlight of the 2010 Oscars. The evening's surprises continued on The Colbert Report, where an interview featured both Tom Hanks and the words "big fat pussy" (Hanks was there to promote his new WWII series). Meanwhile, on The Daily Show, Jason Jones played the Tom Hanks role as he uncovered a Dan Brown–esque conspiracy, complete with an attractive French assistant. Late Night With Jimmy Fallon had a history-making visit from Chris Parnell and Andy Samberg, who performed "Lazy Sunday" live for the first time ever (the song's co-authors, Jorma Taccone and Akiva Schaffer, were also on hand as props). Finally, Isaac Mizrahi made a good case against "foreign mirrors" to Craig Ferguson. Watch our compilation to see what you missed.
