Funny Song. I watched their video on youtube to figure out this tab: 

Standard Tuning

 You'll have to listen to the song the know when to palm mute the notes but its not too bad.

  / = slide 
(#) = optional
  . = palm mute

Bass starts first and holds its note for the whole first part of the song. 
The Bass part is translated for the guitar. The guitar actually comes in after the first bass set.
