On today’s Martha Stewart Show, Jimmy Fallon stopped by to make an ice-cream cake with the potato-chip-laden flavor inspired by his own show. Martha shrieks, “Don’t do that!” as Fallon begins eating the cake’s cookie toppers, and the two discuss how to shorten words for Twitter. Martha’s suggestion for "spatula"? "Spatch," natch. (Jimmy: "How much time are you saving by not saying tula?") See more in the video, below.
