If it helps, I'm betting many folks here identify strongly with the characters they've chosen as their avatars. Maybe we don't look like them (frog help us if there's a real Carl out there somewhere...), but we think or dream as that character might. From what I can tell, Piggy suits Ru, Grover suits Snowthy even better than the Snowths did, Charlie is very much a Fraggle...and I was very much a genderswapped version of Newsie, growing up, and still have dreams as him. So, what's in a pic? A Muppet fan by any other avatar would still act as silly...
Ps. Thanks for the compliment! My sweetie is a cross between Animal & Gonzo...so you can imagine how ridiculously awesome he is. ; )
