The moment Ah Boy's in the bathroom, he starts screaming. I bet the screams translate to these few lines:
"I'm sure we can talk things through".
"I read somewhere on the internet that a cat is just supposed to bathe twice a year".
"I am aqua-intolerant".
"Hey! Isn't that an alien behind you?"
It may be just a bath but it seems like a matter of life and death for Ah Boy.
