My sister sent me these directions on diapering a baby - too funny.

Spread the diaper in the position of the diamond with you at bat. Then fold second base down to home and set the baby on the pitcher's mound. Put first base and third together, bring up home plate and pin the three together. Of course, in case of rain, you gotta call the game and start all over again. ~Jimmy Piersal, on how to diaper a baby, 1968

afterthought: I am guessing this is the only way some men would've been able to diaper a baby.
