I had a cup of tea and a toasted tea cake in a place called "The Muffin Man", so of course my brain was then stuck in "the muffin man" scene from Shrek even though I wasn't in Drury Lane which is near Aldwych/Holborn/Oxford Street. I had to then "google" the words to the song too. See the Wikipedia article.... http://en.wikipedia.org/wiki/The_Muffin_Man
"Do you know the muffin man?"
"The muffin man?"
"The muffin man!"
"Do you know the muffin man who lives in Drury Lane?"
aaaghhhh! "not my chocolate buttons!!"
