I don’t know kung fu

My brother took karate lessons for one week.
My parents were so cheap, they cut an old ratty white bathrobe down to his size.
The instructor turned him away and made them get a real karate robe.
So, for Halloween, he was a karate master, despite the white belt.
Eyebrow-pencil mustache on his lip.
I was given the white bathrobe.
“Two karate masters.”
The next year, he wore some other costume.
And I got the karate robe hand-me-down.
Well, more like “You will wear this and like it, you ungrateful shit”
To this day, I can’t watch Brue Lee movies.
