You know, I once saw a veeeery vague reference to Peter having once been Hank Pym's lab assistant at Empire State (which I assume can't have lasted more than 0.5 seconds), but I was never able to find more specific information, or even confirmation from another source. This makes me sad. I really liked the interaction they had one issue of Marvel Knights: Spider-Man, where Peter was all, "Yeah, sorry my spider tracers are so lame, I invented them when I was fifteen," and Hank's like, "...You invented these when you were fifteen? Holy crap!"
