A group of colleagues go for a night out after work in Singapore...

They join a queue for a nightclub and get chatting to the bouncer.

"So where are you lads from?"

One of the friends replies

"Well I'm from here in Singapore, but my friends are all visiting on business. Kwok and Hung are from Malaysia, Minh is from Vietnam, Liu is from Taiwan, Giat is from Laos, Acharya is from Cambodia, and Arif is from Indonesia."

The bouncer grimaces, and says

"Look, I'm sorry about this guys. You're all well dressed and don't seem like troublemakers. But I'm afraid I can't let you in if you haven't got a Thai."
