Wes and Westley

Wes and Westley are two "chop-busting" coworkers of Low-Five Ghost who specialized in forensics. The pair only appeared in The Postcard and helped High-Five Ghost decode a postcard from his romantic interest, Celia.

Appearance
One is bald and overweight, wears a plain white shirt and suspenders, whilst the other is skinny, wears a brownish business-esque suit, and bears a mustache.

Biography
Wes and Westley are forensic officers who are known for spewing witty insults (referred to as "busting chops") at whomever they come across.

They have worked at the Police Station, presumably before Low Five Ghost did, and help his brother High Five Ghost decipher a postcard sent from Celia.

Trivia

 * They often yell "Just busting you chops!" whenever they insult somebody, just like how Mordecai and Rigby shout "Woah!" occasionally.
