My son needs to knock it off with the pranks!

My 15 year old has been watching pranks YouTube videos and gas been pranking us constantly. It's getting annoying! He got his sister with the Saran wrap over the toilet seat prank. Got his father by putting baby powder on his powered donut. Got me with a miralax prank! It's been everyday some new prank for 3 weeks! Just today I was in the shower and I get covered in flour. I yell "ADRIAN!!!" and he laughed saying "It's not like I saw!" Ughhhh. 15 is such a crappy age!

Edit: UnicornsDoExist... We've had his phone for 3 days 🤦. He could survive without his phone. Only thing I can think is his books since if he's not pranking he's reading.
