42147 - Best song on the planet, and something to do with when (its a date) Leary discovered the effects LSD while riding a bike.
It truly is the best song there ever was in my opinion. I even gave Jeff a picture of him that I took at a roller rink (some place in New Jersey on the In Flames tour) with 42147 written all over the back as a subtle hint. I bet he threw it out, but either way, Curran found it completely amusing.
