Famous exchange from the English Parliment (maybe some British member knows if it actually happened):

Gladstone: "You shall die of a pox, sir, or on the gallows!"

Disraeli: "That depends, sir, on whether I embrace your principals or your mistress!"

Also, from one of the MASH books by Richard Hooker:

"If he could shoot his IQ, Palmer and Nicklaus would be driving trucks!"
