Arm-Fall-Off Boy was a topic of forum and FLGS discussion for nearly a decade before he actually appeared in an issue of Secret Origins.

That reminds me of something I read somewhere, regarding the lamest x-man ever. His power was to know when a phone was about to ring, a second before it did. Does anyone remember where that's from? It's kinda bugging me now.

Edit: Fixed typo. Stupid autocorrect.

I once, long ago, read an article in a Marvel humor magazine about the support group for people with lame superpowers.
Like the woman with super strong and sharp nails - and normal cuticles.
Like the mutant with the ability to detect the calorie conent of any food on touch. He does fight crime - he worked for the FDA.
