876th base

This is the base when you fuck a girl in a banana suit on the moon with an audience of Chinese four-year olds sitting on diamond-encrested llamas wearing toupees made from shaved cow fur sewn together with cum and glue. Also, there is a raja judging whether or not it is good while him and Adam Sandler kiss eachother. This is the base that Chuck Norris won't be able to get to.

Hey! I got to 876th base!
Shut up, you suck.

Naval Base secondary school

The only school in Yishun that is close to an MRT station. And people there are actually very stupid. Only can scream in the corridor like little kids.

They have nice uniform. And a lot of Malay girls there smoke and do TikTok with their boyfriends.

Aliah: Isn't Naval Base secondary school a good school?

Babi: Since when is it a good school?
