'Late Show': Bryan Cranston Was Once Asked To Autograph A Photo Of Fan's Cyst (VIDEO)

"Breaking Bad" star Bryan Cranston was David Letterman's guest on "Late Show" (Weeknights, 11:35 p.m. ET on CBS) Wednesday night.

Cranston reminisced about possibly the weirdest thing he's ever been asked to autograph. He was once in a hospital waiting room when the mother of a patient approached him.

"It would be so wonderful if could you could autograph this photo for me," the woman told Cranston.

He was expecting a picture of himself, but instead the woman handed him a photo of the large fibroid cyst her daugher had just had removed. Nice!

"But when you look at it carefully," joked Cranston, "there is a resemblance!"

"Breaking Bad" Season 5 premieres Sunday, July 15 at 10 p.m. ET on AMC. "Late Show" airs weeknights at 11:35 p.m. ET on CBS.
