Worthless Son In Law

"I can't believe my terrible fate," cried Cu Teo. When his friends
asked what was the matter, he replied "My daughter has gone off and married
that loser who doesn't know how to drink or gamble."
"Then what's the problem?" they asked. "You should be glad
that your son-in-law doesn't drink or gamble."
"Who said he doesn't drink or gamble? He does both. I said he doesn't
know how to do either one properly."
