Whatchamacallit is a brand of candy bar.
When Homer and Lisa were eating candy out of a vending machine at the power plant, Smithers walked by and asked Homer what in the world he was doing. Lisa then offered him some of their candy. Smithers took some Jolly Ranchers and commended Homer on a job well done.
