You know when you give someone a piggy-back or shoulder ride and when they get off you get a weird feeling like your arms are lifting up, well I used to think that if I gave a really fat person a piggy-back, when I put them down I'd spring up off the floor and float off.
I always had to hold on to something after I put my friends down.
