Chingay

Okay, today I was queuing up at a post office to get some stamps.
When I happened to overhear two tourists (Presumably American), Who were also in the queue.
They spotted a Chingay 2008 Poster emblazoned on a wall.

B1 says to B2:
Whats the Chingay parade?

B2
I dunno.... Hmmm. Oh!
It's a gay parade!

B1
Really? How'd you know.

B2
Well remember all of those people we saw in Thailand?
Doesn't the "lady" in the poster look EXACTLY like them?

B1
Oh nice thinking B2, you're a smart one aren't ya.

B2
But, you know what really gave it away?

B1
What?

B2
The name!

B1
Huh?

B2
ChinGAY... Get it?
