Teeheehee..... YES especially when my sister was alive! Lol!
Rarely, but yes, I have done it from time to time.
Generations of teenaged boys (and perhaps a few girls) have rewound the funny bits, but anecdotally-speaking, I think they may also rewind other "interesting" bits.
I'm sure there is a REALLY good joke in here somewhere that won't offend anyone.. Working on it....
Yes, I nearly wore out this scene from The Money Pit:
Sure. Not only that but the most exciting parts. I have a folder labeled "Clips" on my backup drive that has scenes of various movies that were my favorite parts.
Dear Megan Goodgirl,
When I first watched OH BROTHER WHERE ART THOU?
I rewound the whole thing about five times, watching it over and over... that whole movie was so funny.
I also re-watch parts that I consider classic---humorous or otherwise.
Lately, the scene in In the Heat in the Night when Sidney Poitier identifies himself to Rod Steiger as a fellow police officer occasionally gets a rewind.
Same with the final 3 minutes of The Bridge on the River Kwai.
Various movies at various times in my life.
