When "Asses of Fire" is playing, before the "pig f*cker" joke, there is no letter on the couch T&P are sitting on. Shortly after, there is a letter in an envelope on the couch with a Canadian Leaf stamp on it. Terrance has opened the letter. After T&P says "sh*t faced c*ck master", the letter is not to be seen. The letter returns to Terrance's hand.
