One time I hadn't toked for like a week and I came home and of course took a giant rip off my 3-footer as soon as I could. I guess my lungs weren't ready, and I puked all over myself.

Well, it was memorable...

And as for a memorable joint experience, one time during a Model OAS conference (sort of like a Model UN but for the OAS) for high school we had a 20 minute caucus to discuss all the political resolutions we were going to debate. Well, instead I ran back to the dorms we were staying in, grabbed my joint and a lighter, ran outside to a tree between a golf course and a river and smoked the whole thing, and ran back into the conference by the time the caucus was over. Then by some miracle we got to debate legalizing marijuana.
