What are some pranks 2 do on your sisters?

when she is sleeping put her hand in a warm bowl of water. She will pee the bed.

Hold the squirter on the sink down with a rubber band, so when she turns the sink on she gets sprayed.

Go in her room at night and draw a mustache on her with magic marker Lolz.

At night when your sister is brushing her teeth. Sneek into her closet. have a few things that make a small amount of noise like 2 pencils, (when hitting them together) Then after she comes in and is starting to fall asleep make some small noises. after a while she will get freaked out. then after that be quiet for like 10 minutes and then whisper her name in a creepy way. Continue as long as you want. Then as you are leaving say 'i am comming to get you'
