Murray Burns, describing how he apologized to dozens of strangers --most of whom forgave him! The scens ends with this line --

"Well, damn it, lady, that was a beautiful apology. I mean, you gotta love a guy who can apologize so nice. I rehearsed for over an hour. Aw, Sandy, that's the most you should expect from life, a really good apology for all the things you won't get."

My favorite "I'm sorry" moment is from First Wive's Club

Dr. Rosen: He’s found someone new. You’re free. Closure!
Aaron: Yes
Annie: I’m sorry, but that isn’t what this is.
Dr. Rosen: Annie, you’re not helping us out here. Now I’m sorry.
Annie: So am I! Very sorry I ever met you. Sorry I loved you for all those years. I’m sorry I was there for you every minute of every day and supported you in your every move. I’m sorry!

I like the sarcastic, pseudo-sincere apologies for comedic affect.
