Please do not add nonsense to wikipedia 

 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).
