I'll be damned if I can remember the context, probably televisual, but I remember being a small child and feeling sheepishly humbled the first time I heard the saying, "I put my pants on one leg at a time.'
I thought this man was noting his sophistication, because at this time in my life, I thought the appropriate approach to putting on pants was to put a foot in each hole and jump and wriggle until he found himself clothed. This took some doing, as it was the 1980s and I mostly wore skin tight corduroys.
To this day, however, I cannot hear that phrase without feeling a small degree of shame about my rube-like naivete about properly dressing one's self. I'm still not sure I put my pants on correctly.
