I saw a movie a lot of years ago. A kind of meatballs one...

In a part of it, some people try to sabotage a summer resort. One of them was to put blue ink in the shower water tank.

Then some girls taked the shower getting them blue...

Anyone remember it?

It was called "Summer Job." The girl who turned blue responded with a pie, as seen in the clip below.
I remember this one b/c it was on TV as I was a teenager, spending a night in a hotel room with my GF, who let me pie her. After that and other activities, and a shower, we were falling asleep with the TV on when that scene came on. It seemed fortuitous.

Oh! Thank you!!

I've checked the movie and is not the same I was looking for!!😄

Sorry about that; I guess I haven't seen that other one.

The girl doing the pieing in the YouTube clip was completely blue after having blue dye put in her bubble bath.

I've watched it and she got blue from neck to feet... Or are there two scennes like this in the movie?
