Earlier this summer, Jimmy Fallon brought a couple of special guests onto The Tonight Show: a pair of tomatoes that he had grown himself.One was a variety called Celebrity. The audience voted to name it Demi Tomah-to (over Marisa Tomei-to and Timothée Chalame-to). The other was a Beefmaster. Both were small; before turning Demi into a bit of salsa live on air, Fallon joked that he and his guests “might have to split a chip.”
