lets see, I:

- Play video games
- watch t.v.
- meditate (surprisingly difficult when stoned, sometimes easy, it varies)
- eat delicious candy
- listen to great music
- walk around at night listening to music (very common with me)
- post your significant thoughts here (god knows I've done a few of those)
- try to figure out the mysteries of life/the universe.

oh and don't even try reading a book while really stoned. I have and I end up reading the same page over and over till I give up the 10th time because I can't retain the information.
