I thought of this thread a little while ago.
Now that I am the High Goddess of the Pressure Washer at my house, I decided to do the swing that's hangin under our deck. Worked great except of course the water pressure made the swing move around, so I thought maybe I should take it down. Except I couldn't reach the hooks. Hey! I'll just stand ON THE SWING to reach them!
Oh, right, that's probably a bad idea.
