Its ah' me... And because yes...my beard is that awesome.
I assume you mean our avatars and not our profile pictures. I made this my avatar way before people knew who the Superintendent was as a kind of subtle Halo reference. Eventually I grew to really like the idea of having my posts represented by the picture of the helpful happy-looking computer program and kept it.
My username is Undeadpool...that there's a zombie Deadpool
Unless you mean the profile pic IN my profile (people seem to be answering both ways) so I'll say that I attended a live broadcast of the Reefer Madness Rifftrax and we were all given codes to free digital goodies. That avatar pic is the one that most resembles me out of all the others.
