Gordon and Shephard have already got theirs on their profile pages- Gordon has even used his ICly.

Gordon: "Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever." - Lance Armstrong. (Yeah, the man was a performance doper, but it still counts.)

Shephard: "The moment their arms spun freely in our air, they were doomed -- for Man has earned his right to hold this planet against all comers, by virtue of occasionally producing someone totally batshit insane." -Randall Munroe


I'll get you the others shortly.
