here are some i found:

I saw the best thing today... I was around at a mates place and these Jehovah's Witnesses
came around preaching their shit
So my mate invites them in and sits down and offers them pizza and cookies.
After about 15 minutes they left very happy.
We spotted them about an hour later lying in a park staring at the sky
I guess those hash cookies and that magic mushie pizza really did its job.
Who said drugs were bad?!


<potato> A couple years back, my friend had the greatest christmas tree of all
time
<Potato> We were 'round at his place, having a post-pissup drink/laugh at
lightweight bastards and two cops came in because of a noise complaint
<Potato> One of them walks towards the open back door while the other does the
usual "Why are you making so much noise" question routine
<Potato> The friend in question goes pale as he sees the cop stick his head in the
door and only look one way before deciding they were wasting their time
<Potato> When they'd fucked off, I asked him what was wrong, he pointed in the
other direction and told me to go check out the christmas tree the cop
missed
<Potato> I stick my head in the door and lo, a 6 foot tall pot plant,
complete with tinsel and presents around the base, is sitting in the
corner, facing me off, taunting me, goin' "Yeah, fucker, I'm a 6 foot tall
pot plant. Ya wanna piece of me, bitch?"
