Shrek 2 Easter Egg - Fawlty Towers Reference

In shrek 2 when the king (John Cleese) is surprised by the fairy godmother and the queen asks what is wrong he replies "nothing, just an old crusade wound" (or words to that effect).

This is a reference to Fawlty Towers in which Basil Fawlty (Cleese) uses "an old shrapnel wound" as an excuse for various things.
