Into the sea, you'll see, that's where I'll be
Cheng says this is "into the sea," though I always keep thinking it's actually under the sea. This is a really obnoxious song Cheng started singing while playing Alpha Centauri. Alpha Centuari is a game where you build bases on other planets, so when Cheng decided to build some in the sea, he came up with that horrible, horrible song.
Well actually, it's not bad. It's pretty catchy. But in order to properly experience it, you need to hear it for yourself.
