I have to admit I first watched that Clint Eastwood's movie in French : to me, Dirty Harry's "Vas-y... fais-moi plaisir !" isn't as savoury as the original "Go ahead... make my day !".
... Actually, it's on two EFL French teachers' lists online [e-teach & eTeachNet -they're worth mentioning !] that I really got familiar with using this phrase.
