A: Ever since I reached adulthood and stopped growing vertically; I have grown horizontally - then shrunk, then grown again, then shrunk, shrunk more, grown again, and again, still more growing, then a large dramatic shrink ... I could go on like this for hours; let's just say that I have experienced significant fluctuations in weight over the past 20 years.
With a strict diet and vigorous exercise, I once lost 20 pounds in a week. To celebrate, I ate a whole pizza while bathing in caramel. To my surprise, the weight came back.
One time I lost 6 pounds in a day, simply by removing my soiled pants. Here's a hint: If you take a girl home from a bar with the intent of performing the sex act with her, don't tell her that story. She will not be impressed. Showing her the pants will only amplify her horror.
A few years back, I lost 38 pounds in three minutes, without diet, exercise or removing any clothes, when a shark bit my leg off. As a result of the attack, the Boston Aquarium now bans visitors from chumming the water. At least some good came of the attack, in addition to the weight loss.
