the buildup and payoff to the magic hour saga is in my top 3 all time favorite stern show bits.
The other two HAVE to be
Babapology
and ????
The first few moments of 1/6/09 are great with the creepy heartbeat, the 2001 theme, George and then Artie with his "Welcome to Eh-Eh-Eh" comment.
If I was doing a Best of Stern...in no particular order:
Pamela Anderson in the bathtub, calling in and the guys running over there:
Howard talking about his cleaning lady potentially finding his "man-tissue."
Artie in the pig suit...yeah, I know we've all heard this time and time again, but it's STILL FUNNY.
Artie's revelation story
Losers Wipeout
First hour or so of 1/9/06
Playboy Mansion show clips
Anything with Billy and Jackie goofing on the guys
Babapology tape being aired with the live audience
I'd probably throw in some music...Foo Fighters doing Everlong from the KRock studios is a classic. The Alanis Morisette "Everything" was a good one. Third Eye Blind did "Semi-charmed Life" as well.
Almost anything with Beet or Hank.
