1. Causing laughter or amusement.

2. Intended or designed to amuse.

If you laugh, you are probably laughing at someone or something funny. If you wanted to make this happen - just to test to see if you have a sense of humour - you should, according to John Glatbock III, "find a very old woman, tie her up in a rocking chair, put a water balloon in her mouth, drop her into a large, big pit full of lava saying dirty jokes such as 'To control a voodoo dildo, you just have to say to it, Voodoo dildo - the door! to make it make love to the door and so on. But if you gave it to a rather forgettful girl and she doesn't remember the instructions, make sure she doesn't tell anyone the problem. Because she might go up to one lad and he'll say Voodooo dildo - my arse!', let her stay down there for a while. And then you'll hear a loud noise. I won't tell you what it is but if you don't laugh, you have no sense of humour."

Many people have tried this and came back saying that the results were "sick, evil and cruel, yet hilarious". The method is banned on some planets due to the death of many children's grandmothers.
