Hot Diggity Dank! Remember Manny the Hippie? Back in 1996, he was plucked from obscurity off the streets of Haight-Ashbury. And by David Letterman himself, who was in town shooting features for his upcoming San Francisco shows. Manny went on to become a “Late Show” regular, and a national celebrity. So where is Manny now? Well, it took us two months to find him… but we did. Watch Mike Sugerman’s report tonight at 11pm. And only on KPIX 5 News. Followed by Dave’s farewell “Late Show” at 11:35pm.
