Jay's Suprise:
On the second disk go to the cast/crew filmographies section. Select the filmography for Jason Mewes. Once there HIGHLIGHT the button that says "bonus materials". Once this is done press UP. Now prepare yourself for a surprise.

Jimmy V and his keyboard!:
On disc two from the main meno go to the filmographies. On the first page of James L. Venable's filmography if you enter 19 on your remote control (you may or may not need to press enter after entering the 1 and the 9 depending on your player) you'll get to see a short clip of a very young Jim and his keyboard!
