The Worlds funniest practical joke

Ok, so here is the worlds funniest practical joke as voted by me.

All you need is a post it note (preferably yellow) a black ball point pen, a phone book and someone who is not mean and big.

Take the post it note.

Remove from the pad. (it should just pull away from the adhesive strip, if not you may have a defective post it note pad).

Take the black ball point pen and write this on the post it note:

While you were out, a Mr Lyon called for you. Please call him back on 478 3489 asap.

The funny part is that before writing the note, you will have looked up the local zoo's phone number and substituted the 478 3489 in the message above for the local zoo's phone number.

If you are confused as to how this joke is funny, try calling your local zoo and asking to speak to Mr Lyon.

If you made the mistake of trying this on someone who is mean and big, you could divert their attention as they are pummelling you by making lion roar noises (ie Rrrrrrraarrr!!). That should calm them down a bit.
