This a bad move?

I get 22 in big blind. Have about 3500 in chips. Blinds are 100-200. It's a 5.50 SNG with 4 left. Low man with around 1000 moves all in. I put him on AT or AJ. I figured heck, why not. Either double him up and be average, or take him out and be the chip leader. It was a coinflip so I called. He shows QT. Nothing came for either and I won. He proceded by swearing and calling me all sort of names. "How could you call with that weak of a hand?" I liked that considering I had the favorite, barely, preflop. I don't know, maybe it is just me. Let me know what you think.

pocket pairs are better than any draw imho. Yes 22- 66 or 77 are volatile and I wont call or push with more than one raise ahead of me ( usually I wont call an all in with them), but generally speaking, you took a good risk, especially short handed, you had him beat going in, and won. He was a poor sport for yelling at you Short handed your 2s are fine, better than fine.

I also agree with your rationlization on that play. You were able to afford calling him. Nicely done.
