Tip of the day: always remember to pillage before you burn.
Home If you're short on evil ideas, I guess we can share a few. Here are some of the less top-secret ones.

Sponge cake with a real sponge. Shaving cream icing. Be sure it looks realistic.

Stuff pennies between their door and the doorjam. If you use enough they won't be able to get out.

On their birthday, make them hunt for their present. Make clues as to where the next clue is, and make sure they have to run up a few flights of stairs every time. Use tons of clues, with at least a few that don't make any sense, and if you're really evil never have them lead to the present.

Sew the sleeves of their clothes together.

Spray adhesive on their bedsheets one evening

If the area under their bed is always messy, hide some cheese, yogurt, meat etc. under there behind some stuff. Leave it there a few months.

Tear the last 10 pages out of the book they're currently reading and paste in your own artfully written ones.
