These photographs, snapped by a fan who bumped into Tom in a restaurant, are going gangbusters online, with bloggers hailing them as "definitive proof that Tom Hanks is truly awesome".
Fellow actor Bill Murray has a similar reputation for awesomeness. He's known to randomly crash people's parties and whisper, "No one will ever believe you" to a guest before disappearing into the night.
He recently announced a party crashing tour of the US. We reckon Tom Hanks should join him!
