Well, we can say one thing about Piers Morgan‘s new show, he’s already brought Leno-bashing back into style. Howard Stern was Morgan’s second ever guest last night, and went off on a pretty impressive anti-Jay Leno tirade. Lot of history there. Leno stole longtime Stern guy “Stuttering John” Melendez and brought him to work on the “Tonight Show” over a decade ago. Stern’s visceral reaction to Leno was one of the few moments he broke character last night. Guy knows how to hold a grudge.
