While celebrating Christmas with George Smythe and his family in 2004, the First Doctor, Barbara, Ian and Vicki were told the joke, "What's yellow and swings through the jungle?", the answer being "Tarzipan" (a combination of Tarzan and marzipan). Vicki, who had never heard of marzipan, didn't get the joke. (PROSE: Every Day)
