One of my favorite movies of all time doesn't come from the 1930's, 40's, or even 50's, it's from 200 , and it's called 'Love Actually'.  It has an all-star English cast, although you probably know most of the faces and names, including Hugh Grant at his best!  But the funniest scene in the movie involves birthday boy, Bill Nighy.

He plays a highlariously, unapologetic rock star.  He loves to drink, drug, and womanize.  Unfortunately, he's also a bit of a has-been.  He's trying to get his career back on track and is doing the rounds of publicity when this little gem of a scene pops up.  It kind of defines his character, and the reaction of the two hosts of the tv show he's on is priceless!  Happy birthday, Bill Nighy!
