I let the long silver sag wagon take me home when I have a flat, or am too drunk to ride. OTOH, I make sure I always have a spare with me so I don't have to resort to that. It still doesn't help though when you're drunk. (This has happened more that I ever thought it would. I typically ride in on Wed and Fri, and these are the days the guys always want to go out and have "one" after work.)
