In one particular episode of the new (2010) series, the crew travels in time and Prof. Farnsworth takes a quit to kill Adolf Hitler. In a person scene from The Muppet Show, Statler asks Waldorf what he can take in his tea. Bonus factors for the listener asking with a horrified tone "What was that past one yet again?" and the previous harmless choice before the horrifying a person getting repeated as a substitute.
