When the man loses his shit

The report says that halfway through the flight, a guy in first class loses his shit.
He’s a science teacher, and the pull tab on his soda can uses a second class lever.
“I thought this was first class!” he shouts. “I want a first class lever! Effort, Fulcrum, Weight! ”
He starts hitting the flight attendant with a pillow.
“Stop!” she shouts. “That’s also a second-class lever!”
And he stops long enough for the marshal to knock him out.
How a science teacher affords first class, I dunno.
And how a flight attendant knows basic physics, that’s a bigger mystery.
