I love practical jokes and would like to get a few people this year but I am stuck on ideas. Can you give me any ideas or share some practical jokes you have played in the past?
A couple of years ago I told my very doting and trusting MIL that her 6mth old grandson had just got up and walked across the livingroom. She squealed with excitment and promptly told all her work colleagues whilst she was still on the phone with me. I truly felt awful when I had to reveal it was an April Fools! 
I have in the past placed cling film over the loo and replaced the sugar jar with crap-a-lot sugar from the joke shop. I have also managed to convince my younger sister to pop to the shop to fetch me some elbow-grease.

I am looking for inspiration!
