The Plumber Crack gag is a classic comedy staple. It is a situation in which a plumber or other blue-collar worker of similar ilk bends to do some task and exposes their butt crack in the process to onlookers.
Common stereotypes of the Blue-Collar worker are their apparent lack of hygiene and personal fitness. Keeping in mind the principle of Show, Don't Tell, the (usually) overweight and hirsute character bends down to take a look at something, and their pants fall or get pulled below their waistline.
