Could be. Way back in the early to mid-90's, Marvel issued a monthly Preview book (similar to the one they have now, only it wasn't married to Diamond's Previews) & every month they had a section which they called "Marvel's Silliest Moments". It covered such debacles as the Thing becoming a pirate, Galactus trying to eat Impossible Man's planet, &, of course, the Iron Man nose.
Oddly, though, I think the 90's as a whole qualifies as one of Marvel's silliest moments.
