One of These Men Farted in the Elevator

SCENE:  Wannabe Governors Ned Lamont and Dan Malloy ride the elevator together prior to their televised death match debate in West Hartford.

Ned: Did you fart?

Dan: No. 

(pause)

Dan: Did you fart?

Ned: No.

Dan: Well, one of us is lying because there is an awful farty smell in here.
