This must be so sweet a victory lap for Larry David. Decades ago, in the 1980s, he was a writer for Saturday Night Live, but only lasted one year – and in that year, got only one sketch on the show. He and another under-utilized SNL alumnus from that period, Julia Louis-Dreyfus, turned around and reteamed for a little show called Seinfeld – then reteamed again for a full-season Seinfeld “reunion” story line on his subsequent hit series, HBO’s Curb Your Enthusiasm. And now, after all that, Larry David has killed it this season whenever guest starring to impersonate Bernie Sanders – and tonight, for the first time in his career, Larry David gets to appear on SNL as guest host. The musical guest: The 1975.
