The funniest thing i've done high was probably buying 5 pounds of swedish berries because half of me thought that filling the bag would be a pound, and the other half thought that all that was in the bin was a pound. After filling for a while, i looked at the bag and thought "shit, that is a LOT more than 1 pound." So i spent about 20 bucks on swedish berries.
The thing i most laughed at was during an hour and a half long christening sesh for my friends new bubbler.About 30 min in, my one friend had packed the bowl waay too much, and so we thougt it was done about when it wasn't. We tell the guy who packed the bowl to finish it off with one massive "god hit". So he tries, and goes until he can't anymore, and precedes to cough until he, laughing his head off, pukes ice cream over the side of the playground we were at. After laughing for about 10 mins, it still took us about 10 to finish the bowl we thought was done, and the guy who puked kept going with us for the rest of the time, like an hour. The rest of the night was mostly just saying "god hit! god hit!", which now means you puke, and "he actually puked! and kept going!"
overall, a good time was had by all.
