Take 2: The Party at Jimmy Kimmel's House

George Clooney, Ben Affleck, and Jon Favreau were just a few of the A-listers at the annual event

Howard said he'd also been to L.A. over the break and attended yet another party at Jimmy Kimmel's house.

Most of the guests made a point to talk with Howard but, of course, he was most interested in the guests who didn't say hello. Howard didn't learn until afterward that he'd unknowingly stood, for quite a while, next to Ben Affleck and Jennifer Garner.

"I had no idea they were at the party ... why didn't they say hello to me? It was supposedly a party in my honor," he wondered.

Howard said he was talking to Jon Favreau at the time, but he would've gladly turned away if Ben and Jen had just said hi. "I would've dumped Favreau in three seconds," Howard joked.

He had better luck with other A-listers, including "a big long conversation" with George Clooney and his girlfriend, Elisabetta Canalis. Howard reported that Clooney knew just about everything going on lately on the Stern Show.
