Brief tickle in Marx Bros. movie?

The other day I was re-watching the Marx Brothers movie A Night at the Opera, and noticed for the first time what just might have been a quick tickle during the stateroom scene. I'm not claiming it was definitely a tickling scene - it's one of those where it's really hard to tell - but one of the actresses seemed to give a brief giggle, so maybe there was something.

Here's a clip of the scene; the tickle, if there is one, happens around 45 seconds in.

Ha! I never caught that one before and in fact, I had to watch the clip multiple times just now to catch it! Super fleeting and obscured! But I think you're right.

Harpo gives a quick tickle to a cutie in a restaurant, in "A Night In Casablanca" at about 55 seconds in.

I was laughing, it's always good to see the Marx Brothers do ANYTHING....the tickle itself is nothing (in both clips)....but good for completists!

Thanks, Hemmen!
