Prank 1... An old classic.

Place cling film (plastic wrap) accross the toilet bowl and lower the seat.

Prank 2...

Add a thin layer of Vaseline to the toilet seat. Your victim won't know what it is.

Prank 3...

Wait until you're sure the toilet will remain unused for at least 24 hours.

Get 2 - 3 packets of powdered jello and mix it into the toilet water until dissolved.

Let it set. (The more jello you use the harder it will set)

prank 4...

Fill a large brown envelope about 70% with shaving foam.

Close over the flap but don't seal it.

Place it part way, flap first under a friends door and call them to get it.

When you hear them walking towards it, jump on the back end of the envelope and shaving foam will spray everywhere.

When you visit your friends house, put a squirt of washing up liquid in their dishwasher. Next time they run it suds will come oozing out the door.
