“There’s something funny about a fat guy and a skinny guy together.”
And words with the ‘k’ sound. In the Neil Simon play The Sunshine Boys, Willy explains: “Fifty-seven years in this business, you learn a few things. You know what words are funny and which words are not funny. Alka Seltzer is funny. You say “Alka Seltzer,” you get a laugh . . . Words with “k” in them are funny. Casey Stengel, that’s a funny name. Robert Taylor is not funny.” -
