Yiddish gone wrong

I need you like I need luck in a cup
Put a  lock on the cop
Look in the coop
Look at cops?
Speak Afrikaans, good luck!
Knock for  headlock
I lack a cap.
Kippah on  the rocks
The super and the  dreck
The beige and the black
Greed fated my socks
Lines on the  dock
Unemployed and sick
Brexit, go f*ck!
