Is the Tick moonlighting as Captain America?

In the Got Milk? commercial where the milk man accidentally goes to the Superhero tryouts, is Putty the guy in the Captain America costume?

Putty seemed ok in that show, but what can they do for a second and third episode? It ran out of novelty during the first one.

I’m gonna say no, because I usually recognize him when I see him and go “Puddy!” and I never have during that commercial. But then, what do I know?
