What is the best prank あなた have ever pulled?

Um.. ive never pulled a prank...
Im lame , i know.

I told my mom she had a bit of dirt on her nose. On April Foll's Day. She fell for it hook, line, sinker.

Not really a prank, but whatever.

Scared the shit out of my younger cousins によって telling them there's a flesh eating shape shifting monster on the loose!

They actually fell for it!!

ewe

Well my mom hates lizards, so i took one of the fake stuffed ones i have and i put it in her slipper so when she went to put them on she literally jumped like a cat scared at something, oh and she screamed. Meanwhile i was laughing xD
