"personaje cuya simpleza provocaba efectos cómicos"
Yes I do understand and that it means ; a person whose simpleness provokes comic effects.(litterally)

It goes a bit far to dig out Spanish history of theater.
I brought up the guinea pig because they also are pretty comic pets besides being champion reproducers and sharing the word.

As this all came from: bobo. When I look up bobo it still seems to go with modern theatrical items.
