Knock, knock — In Jerry Seinfeld-speak, what’s up with waterboarding? Sen.Richard Burr (R-N.C.) cracks a torture joke during the hearing on John Brennan’s nomination to head the CIA. (Sen. John McCain (R-Ariz.) has used the same material during the confirmation hearings for Secretary of State John Kerry.)

Congressional chuckles — Speaking of humor, at the Washington Press Club Foundation’s annual congressional dinner, the two performers — Sen. Heidi Heitkamp (D-N.D.) and Rep. Jason Chaffetz (R-Utah) tried for some yuks.

Think twice, tweet once — A tasteless tweet takes down another House staffer.
