“What I couldn’t stand was being cold. Lying out on the beach in the surf, stripped down, freezing my ass off—that was the worst. I’d lock arms with the guys on either side of me and “jackhammer,” my body vibrating crazily with the chills. I prayed for someone to pee on me. Everybody did, I’m sure. Urine was about the only warm thing available at that point. If you happen to look out on the surf during a BUD/S class and see a bunch of guys huddled together, it’s because somebody out there is pissing and everybody is taking advantage of it.”
