Fortunately, the accent was Chinese and did not sound like they had any ill will, but just general confusion. There's many foreign students training in the LA basin.

Another one, heard on the LA CTAF while an apartment complex and a fire helicopter had responded:

"You know, it works best if you put the water *on* the fire..."

While monitoring 123.45 over northern Alabama today, heard this funny sequence.

pilot one: Kitty Kitty

pilot two: Meow
pilot two: What are you in?

pilot one: your ex-girlfriend

^^^ Haha that's awesome.

Was flying in an area where controllers occasionally call traffic "targets."

App: Cessna 123, traffic, the target is at 1 'o clock and 5 miles
Cessna: Cessna 123 has target in sight
Unknown AC: Too close for missiles, switching to guns!

Another one when I was working for 9k

Fellow Aircraft, on Company: Cair XX, say airspeed
Me, on App: Yeah Cair XX, we're still climbing so ah.. uh... wait, was that approach?
Approach: Um... what?
Me: Uh disregard...
*Sniggering and several d'ohs on Company*
