It's our favorite big brother! Jerry Trainor is known best as Spencer, the silly sculptor and big brother to Carly on iCarly. But did you know he's also the voice of Dudley Puppy on T.U.F.F Puppy? This guy's a comedy king and a top dog! But Jerry really got his start on Drake & Josh (just like Miranda and Nathan)! Jerry played "Crazy" Steve on the show, and he was such a hilarious hit that he was signed on as Spencer Shay. And thank goodness! We just couldn't live without this wacky wisecracker.
