His Bookman character on Seinfeld is so profoundly funny that I've seen it now at least 10 times and I still laugh out loud. It's close to being the funniest non-Norm MacDonald non-Mitch Hedberg non-Bob Newhart tv thing evaa.
Larry Storch was great in everything he did, and he was in everything in the 60s. RIP
His brief scene in Columbo was pretty good. It seemed like half the driving testers at the CA DMV back then had this personality and Larry captures it perfectly.
Wonderful, memorable character actor on lots of shows and movies, including various iterations of Star Trek, Firefly, and - most famously - as President Charles Logan on 24.
