Although it is tempting please don't include lines that have stuck in your mind merely because you like them or you think they are clever. Catch phrases need to be reasonably recognisable. However, if there are any other lines you really like you can list them seperately. Here's some I can think of...
"You stupid boy."
"Don't panic!"
"Put that light out!"
"They don't like it up 'em!"
"The Vicars not going to like this." (or is this pushing it?)
Other lines that come to mind:
"Oh you silly little man!" (Vicar shouting after being run off the road on his bike.)
"Would you mind awfully just falling in,in your own time?" (might be some what of a paraphrase)
"Don't tell him Pike!"
"It was all bone and bristle."
"They've scrrrewed 'im dooon."
"Damn the bloody bank!"
