Well, Tom Hanks did do a movie called Big..... That should have been our first clue.

But, it does seem improbable that boy-next-door-nice-guy-Gump has secretly been hiding a giant schlong under those relaxed fit trousers all this time. But it's true. Believe us, Popdust has it on very good authority.

“Tom was famous for being well-endowed back in college," a friend of the Oscar winner confides exclusively to Popdust. "He was always a nice guy, don't get me wrong, but he was also more than a bit of a playboy. Word of his endowment traveled fast and Tom basically had his pick of all the most popular sorority girls."

Tom and his BSD (big swinging dick) eventually graduated and moved on to other venues.

“He would never let on, but Tom has always had a way with the ladies," the pal dishes. "He's confident without being arrogant, and he can talk to anyone—the most beautiful woman in the room, or the bus boy."

Eventually Tom, dick, and hairy, settled down and put that appendage to good use—He, and first wife Samantha Lewes had two kids together; Colin and Elizabeth.

However, after deciding he still had some bullets left in the chamber, Tom left Samantha and ended up marrying his current wife, Rita Wilson, and they have two sons together, Chester and Truman.
