Funny scene in the elevator

I and my officemates decided to take a break from our usual office task to buy something at the convenience store. the ride going down the building was too long since we are from the 25th floor, so an officemate of mine decided to teach the new editor (who is Thai) some basic Tagalog stuff.  

Chinese Editor #1: (to Thai editor) I will tell you a very important Tagalog word. Say "Siraulo".

Thai Editor: "Siraulo"

Chinese Editor #2: You tell him (Chinese editor #1) that.

Chinese editor #1: No, you tell her (Chinese editor #2) that.

Thai editor: I'm going to use that to both of you. 

That cracked me up and some other people that we were with inside the elevator!
