Noah, it's very weird that you should bring this up now, because a few hours ago I was going through some boxes of college stuff, found my old journal, and actually read the entry for April 7, 2001 (for the first time in at least a year). In that entry, I do, in fact, note the once-in-a-lifetime coincidence of four happily occupied roommates, along with some other details that I can't quite bring myself to blog. However, I will quote one classic exchange from that evening. Noah might remember it (he was there):

She: I was at rugby practice. I've been tackling women for two hours.
Me (wistfully): It's been a long time since I've tackled a woman.
