Mistakes you only make once

When I was in middle school, I started becoming interested in cars and would help change the oil on our cars. Well, my mom had this 4Runner and it had a skid plate on it. I had never seen one before so I was having trouble finding the drain plug for the oil pan. Eventually I looked back a bit and found a drain plug. Perfect. I got the drain pan, pulled the plug....and the oil looked weird. I'd never seen red oil before. Needless to say, my dad was pretty mad and promptly told me that I drained the transmission and not the engine. These 4Runners have sealed transmissions with no dip stick tube, so he got to spend the rest of the afternoon under the car with a turkey baster filling the transmission through a vent hole.

That was a mistake I only made once.
