VIDEO : Tom Hanks Ponders Life's Biggest Questions With Stephen Colbert

Tom Hanks stopped by The Late Show With Stephen Colbert on Wednesday and ended up getting deep . . . real deep. After Stephen admitted that he sometimes likes to mull over life's biggest questions, he called on the actor to take part in a segment called Big Questions With Even Bigger Stars. The two then lay on a picnic blanket in the grass, took in the "scenery," and dove right into some of the biggest mysteries that plague us all. Stephen asked, "What would you do with a time machine?" Tom hilariously responded, "What would anyone do with a time machine? Go back in time and hold myself as a baby."
