1. Stuff a toilet paper roll with whatever fluffy material you can find and stick it to the back of the bathroom door. When your friend goes to flush, it will surprise them!
2. Clip a few colorful balloons to the back of the toilet seat. Watch your friend's expression as they try to sit down and the balloons unexpectedly pop!
3. Put a few drops of brightly-colored nail polish remover onto a cotton ball and tuck it into your friend's tank top or shorts. They will be so surprised when the fabric starts turning colors! 
4. Place a roll of toilet paper over the edge of the bathtub or sink and set a timer for it to unroll over the course of the day. When your friend goes to use the bathroom, they will discover the unexpected surprise!
