When I saw Spamalot, during the Knights of Ni scene, the main Knight said "We are the now the Knights of ICKI ICKI ICKI BEKLANG SCHWING..." and went on in gibberish for a few moments before breaking into a chorus of "London Bridge". He then broke into a fit of histeria, including everyone onstage except Arthur, who was being played by Harry Groener then. He was completely straight faced the whole time, but the entire remainder of the scene the head Knight was cracking smiles.
