Now known as the scandalous sketch (direct Spanish translation) the comedian Santiago Bal tries to assist a young lady who is bothered by a flea that is itching her and endeavours to assist with her clothing...you know the rest.
Humour has changed and the Benny Hill (groan) type of sketch doesn't go down as well as it used to nowadays. Personally, I found anything Benny Hill did to be cringeworthy anyway.
I suppose the point is, if a woman wants to perform in silly sketches like this, is she being demeaned even though she chooses to do it in the first place. I don't think so - it's on her if she knows what's coming.
