If your language has its own word for the concept of taking pleasure in other people's misfortunes, you don't need to have any great comedians (left [0]) to be able to laugh.
Part of the family of haha, hehe and hihi is höhö in German, which can be used as a sarcastic laugh to a particularly bad joke, halfway between a ho-ho-ho and a hehe.
Also when speaking out loud, the pronunciation of lol in German is always "lol", as a word. I believe in English-speaking countries the letter by letter l-o-l is more common.
