Okay, a few years ago in the Zits comic strip the lead boy and his two friends spent a two week story arc wearing empathy bellies, technically not pregnant but I imagine as close as they could get on the subject, the only problem is I don't necisarily remember when this was, anyone out there have any idea what I'm talking about and willing to help track this down?

I figured if I could get help finding this anywere it would be here.
