The eight Lord Tweedsmuir Secondary School Grade 12 students streaked through their school cafeteria — an annual tradition.
"I just had shoes and Mexican wrestling mask on," said streaker Dwight Lilly, whose older brother pulled the same prank at the school a few years ago.
Fellow streaker Griffin Steele says they thought they'd be suspended, but instead the prank resulted in the boys being banned from their grad ceremony.
"And I was like, 'I'm an only child so my parents only get to come see one person graduate ever in their life. Isn't there anything we can do to fix this?'"
Steele says the school could have come up with another form of punishment.
"They could have given us a suspension — I'd be fine with that," he said.
"I didn't mind writing my tests later cause we suffer for it cause you don't get to write your test with the rest of your class — it's a little harder. I think that's punishment enough. It's not like we hurt anybody, we didn't cause massive damage, and then you're going to take away something that somebody only gets to experience once? It's ridiculous."
The Surrey School District says no specific rule governs grad pranks, but the punishment is not unheard of.
