I noticed the Gabe thing too. One he's a Reporter, a western card sharp, and in another he's assistant to a private eye, etc. He always seems to have a girlfriend or a way with the ladies, too. I think HalLane hit it on the head.
I hate to say this, but I actually like these BB films more than the East Side Kids films. More like they are a comedy team. Huntz Hall is really fun now matter what he is doing in these you seem to always have your eyes on him whenever he is on screen.
And what's with Louie's head???
