Though the comics that I've designated Unfunnies usually existed solely to fill space (or possibly they were part of some attempt to circumvent mailing regulations, I've never been too clear on the nitty-gritty), every once in a while DC took a stab at sneaking a little extra advertising into one, and I'm sure that they never found a more willing shill than the odious Little Pete:

Not only does Dr. Means reinforce Pete's lying ways, but he jumps on the cash-fuelled Trik-Trak bandwagon without hesitation.

Here's the regular ad that ran in DC books about the same time:

Note that Trik-Trak was made by Transogram, makers of Ka-bala, the incredible home occultism game, and that Ka-bala is the other product that was stealth-advertised in an Unfunny. What does this all mean? I have no idea.

- Little Pete's shame was found in Challengers of the Unknown No. 44, while the Trik-Trak ad is from Aquaman No. 19.
