Quote from : Star Wars: Episode V - The Empire Strikes Back Movie

[trying to fix the hyperdrive]
Han Solo: Horizontal boosters. Alluvial dampers? Ow! That's not it, bring me the Hydrospanner. I don't know how we're going to get out of this one.
[the ship is hit, causing the tool box to fall on Han]
Han Solo: OW! Chewie!
