A: "My friend, you wanna bank with me?"
A: "How much?"
You have to understand the culture of kum-kum banking in Cali casinos to appreciate why this is funny. Or actually you don't. An equivalent dialogue would be something like,
A: "Hey you wanna go on a date with me?"
A: "When should I pick you up?"
...but it's funnier than that really, because it's in this environs where everyone lies and no one listens to each other and...oh forget it.
...the other funny exchange which I almost forgot:
A: "Today is Chinese Father's Day."
B: "Really? I didn't know there was a Chinese Father's Day."
A: "It's today."
B: "Happy Chinese Father's Day. Is there a Chinese Mother's Day?"
