well...that's easy. Over at a friends for a puff-n-pass party and got sooo stoned... I figured out how time travel was possible. I totally freaked everyone and the room got real quiet.
They all thought about it for awhile... then went back to party as usual. Bad part was... people I didn't even KNOW who were at the party came up to me a few weeks later and wanted to know if I wrote any of what I said down...cause they wanted to send it off to some scientists they knew. (funny thing, also...people at this party were mostly engineers ansd scientists)
I now carry a small MP3 player with voice recorder for just such an occasion. When you get so stoned you figure out time travel...you just had some dank stuff!
