"ones"? That would seem to imply you did it more than once.

My cousin gave me a gallon bag of the stuff once... it was all he had left and he just wanted to be done with it. I packed a bowl in my bong and had a huge hit. It last about 10 minutes and I saw some pretty fun stuff (stuffed animals getting up and dancing), but the overall experience was not fun. I handed the rest of the gallon bag off to a friend. That was over 20 years ago and I'm pretty sure that same bag is probably still being passed around.
