As they say in the movies, "oh be-have". Seriously, though, we are trying to write an encyclopedia here, so don't make joke edits. Some readers looking for a serious article might not find them amusing. Remember, millions of people read Wikipedia, so we have to take what we do a bit seriously here. If you'd like to experiment with editing, try the sandbox, where you can write whatever you want (as long as it's not offensive). Maybe you should check out Wikipedia:Bad Jokes and Other Deleted Nonsense.
