(CBS) — Former Cubs pitcher Ryan Dempster was known for his laid-back, playful attitude when he was in Chicago.

Oh, and then there was his dead-on Harry Caray impression. (Or, was it really Dempster doing an impression of Will Ferrell doing an impression of the late, great announcer?)

On Wednesday, the retired pitcher was in Pittsburgh as the Cubs won the wild-card game against the Pirates to advance to the NLDS with the St. Louis Cardinals. With the champagne spraying, Dempster was only too happy to indulge in a little Caray-ing on.
