This was sent to me by a friend of mine. Please feel free to add additional ones more relevant to model engineering. My fave is the engine hoist one. 
Tools explained.
DRILL PRESS: A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it
smacks you in the chest and flings your beer across the room, denting the freshly-painted project which you had carefully set in the corner where nothing could get to it.
WIRE WHEEL: Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also
removes fingerprints and hard-earned calluses from fingers in about the time it takes you to say, ‘Oh sh–!’
SKILL SAW: A portable cutting tool used to make studs too short.
PLIERS: Used to round off bolt heads. Sometimes used in the creation of blood-blisters.
BELT SANDER: An electric sanding tool commonly used to
convert minor touch-up jobs into major refinishing jobs.
HACKSAW: One of a family of cutting tools built on the Ouija board principle… It transforms human energy into a crooked, unpredictable motion, and the more you attempt to influence its course, the more dismal your future becomes.
VISE-GRIPS: Generally used after pliers to completely round off bolt heads. If nothing else is available, they can also
be used to transfer intense welding heat to the palm of your hand.
OXYACETYLENE TORCH: Used almost entirely for lighting various flammable objects in your shop on fire. Also handy for igniting the grease inside the wheel hub out of which you want to remove a bearing race.
TABLE SAW: A large stationary power tool commonly used to
launch wood projectiles for testing wall integrity. May also have value in quickly removing various fingers and thumbs.
HYDRAULIC FLOOR JACK: Used for lowering an automobile to the
ground after you have installed your new brake shoes , trapping the jack handle firmly under the bumper.
BAND SAW: A large stationary power saw primarily used by most shops to cut good aluminum sheet into smaller pieces that more easily fit into the trash can after you cut on the inside of the line instead of the outside edge.
TWO-TON ENGINE HOIST: A tool for testing the maximum tensile
strength of everything you forgot to disconnect.
