Tom Hanks, known for being wacky on Twitter, was walking down the street when he saw a lone sock, and wondered who could be so footloose as to just leave a sock on the sidewalk.

What resulted between them was two celebrities acting like they're not celebrities, but rather two dudes who know each other on Twitter.
