Leak stain on ceiling:
Cut a piece of plywood into a square. Nail it over the stain. Put a handle on it. Tell everyone it's the door to your attic. (Not recommended for basement apartments).

Crabgrass:
In one corner of your lawn, assemble your mower, rake, shovel and weed killer. Using right index finger, dial any asphalt company. Have them come over and pave your lawn -- mower, rake, shovel and weed killer included.

Cigarette burn on rug:
Cut one lemon in half. Squeeze juice into large glass of gin mixed 50-50 with tonic. Add ice. Drink enough glasses of this solution until burn becomes blurry. Move couch over mark.

Dirty paint brushes:
Soak brushes in pail of paint remover. Read paint remover directions carefully. Notice they say solvent should not be inhaled. Move brushes and can to airy place -- like the backyard. Notice that solvent can kill grass. Move can and brushes up off lawn onto suitable surface like, say, barbecue. Now notice that solvent is highly flammable.

Annoying drips:
Don't invite them over anymore.
