Now, 'Anonymous', (who is so extremely well known & loved she is now like 'the guy formerly known as prince' whose fame is such they just don't need a name), the film you are referring to is the Parisian romp, "Charade". Outside AH's apartment door, CG tells AH, "How about a spanking!" AH responds spiritedly, "How about a bunch of fives?!"
Your right, spanking AH would be devine but she always played such good roles, in more ways than one. And how about being spanked by CG, oh transparently 'Anonymous' one?! By all reports CG, got plenty of practice with DC in real life, so he would surely have measured up!?
Now I've let 'the cat out of the bag', (get it!), I guess it's too late to take up your bet?!
BTW, I really enjoy a good 'over the shoulder' carry, too, especially if combined with a few nice whacks. Another one I recall is Juliet Lewis getting hoisted up & lightly spanked by her screen boyfriend in some movie set in American suburbia. Can anybody pick this film?!
Thanks for your cunnundrum,
