Even though it's obvious that you speak English as a
second (or so) language, you get the concept... and you're
making it work for you.

To answer your questions, I really think that you're
doing the right things. When that girl hit you, you turned
it around and made it funny.

Telling a girl that she's cute like a cartoon is a
nice touch (I'm still hoping that's what you meant).

If a girl tells you that you're too funny, just say:

"That's impossible."
