Pranks

Hey I wanna pull of a good prank on my brother, any ideas? also make it reasonable he's 12, and make it where it's not incredibly bad, so any ideas?

Stick a thumb tack to the inside or a door handle, so when he tried to open the door he gets pricked. If your not that mean or just don't want to cause him bodily harm, try the same but with toothpaste instead.

When I was a kid I used to pray every night for a new bicycle.
Then I realised God doesn’t work that way, so I stole
one and prayed for forgiveness.

Pour a pack of Jell-o mix into his own toilet (if he has one) in the middle of the night. When he gets up, his toilet will be full of Jell-o.

I win.

I say you take it a step further and do it to his bathtub.

my brother has that too ,maybe a good spider trick

Or; heres a good idea:
Hide somewhere in your brothers room at nightime (preferably a curboard or under the bed), see if you can find a mask or a synthetic hand (a claw or something) and creep your hand slowly onto his body. Or prehaps you could buy a rubber knife, put a ski mask on and pretend to rob the house and hold him randsome! (Its cruel though)

Urinate on his mattress. That usually gets a few laughs.

is that what you do?

I'd go with the Jell-o!!!
