WD-40 (the original name was Water Displacement #40) is very versatile. In addition to getting rid of our squeaky door jambs, we can:

Remove stuck lego pieces
Spray the stuck part to lubricate and make it easier to pull apart.

Loosen a stuck zipper
Spray on stuck area and wiggle the zipper up and down.

Prevent flower pots from sticking together when stacked
Just spray the sides.

Clean and lubricate guitar strings
After playing, spray on WD-40 on a rag, and wipe the rag over the strings. This also helps prevent corrosion.

Preserve your jack-o-lantern
After you're done carving, spray liberally on the outside with WD-40 to add a protective coating. If you plan on using a candle, wait at least 24 hours before spraying.

Remove bumper stickers, decals, price tags and other sticky stuff
Just spray directly with WD-40, wait 30 seconds and peel it off. It even removes all traces of duct tape.

Make shoveling easier
Spray shovel with WD-40 so dirt/snow slides off easily.

Keep pigeons away
Spray your roof/balcony/patio furniture with WD-40 (they hate the smell).

Unstick gum from hair and carpet
Spray WD-40 directly on the gum, wait a little bit and pull the gum free.

Splinter-free wood tool handles
Rub WD-40 directly on wood.

Clean, lubricate and protect leather furniture
Spray WD-40 directly on the furniture and buff with a soft cloth.

Remove black scuff marks off kitchen floor
You don't have to scrub nearly as hard to get them off... just make sure to wash off after use.

Eliminate dead-bug remains from your car
Don't delay... bug guts eats away from the finish of your car if not removed quickly.

Great for umbrellas
Spray the stem to make it easier to open and close.

Whiteboard cleaner
Spray some WD-40 into a folded paper towel and rub out stubborn marker stains.
