Couple of great Churchill ones:
Woman at party: Mr. Churchill, if you were my husband, I'd put poison in your wine!
WC: Madam, if you were my wife, I'd drink it.
Bessie Braddock: Mr. Churchill, you are DRUNK!
WC: And you, ma'am, are ugly. But in the morning... I shall be sober.

"I spent most of my money on booze, women and fast cars. The rest I just squandered." -George Best
And a couple on which I'm unsure of the attribution:
"Christianity has not been tried and found wanting. It has been found hard, and not tried."
"If two people agree about everything, one of them is unnecessary."
