A lot of viewers has asked what the chords are and I reckon these are fairly accurate.
I've tabbed this song the first time as G D Am C, but it's not as close as this one.
I've put them on YouTube though it'll get buried in the comments so here's a more 
readable version.

Chords used are as follows (I'm not certain if the names are correct).

sounds better with C#)

This is also pretty much the same as the Nom Nom Nom Nom Nom Nom Nom song...
