Drop Dead Diva
Gunn's been given brief walk-on roles on Ugly Betty, the cinematic horrorshow that was Sex and the City 2, and his voice was even used on the animated American Dad!, but it wasn't until last year that Drop Dead Diva finally allowed him to exercise thespian chops, screen presence, and actual character work (even if he was playing himself).
How I Met Your Mother
As Barney Stinson's personal stylist on an episode of How I Met Your Mother this season, Gunn was almost secondary to a classic Neil Patrick Harris meltdown, but his stoic, lovably stilted delivery make this cameo one of his better endeavors and a step above an average season six episode of Runway.
I Get That A Lot
In his weirdest bit part to date, Gunn acted as a real-life fast food worker pretending not to be Project Runway's pinstriped consultant. A few customers called him on the gag immediately, while others (namely a fellow with an "Abe Lincoln beard") needed to be clued in. Awkward and endearing.
