So my substitute yoga instructor today was utterly off her rocker. It was the Suzanne Sommers approach to power yoga. With an impossibly bubbly voice, she put us through various contortions, all the while commenting on how groovy it all was. The high point was when she told us to stand with our legs "four or five feet apart, about one Kylie Minogue." An even better unit of length than the Smoot.
