The only rules I follow are:

1) The person who rolled it, sparks it!

2)Puff puff pass!! I hate it when people talk there asses off when its there toke..I hate watching it burn in there hand, when it could be going through the rotation!

3) pass it to the left! (don't allways follow this rule when its just me and the x-wife)

thats about it...I like some other peeps rules though
