I like #8...... Another thing thats very very effective.. Getting those Hershey bar looking chocolate ex-lax..you can either re-wrap in a hershey wrapper or... my favorite.. melt it and make fudge.. my mom did that...she mixed it in with chocolate chips.. My dad and his niece pissed her off... They ate the fudge and I swear they shit for days.. You might wanna use 2-3 bars..
