Sitting on the shelf, the PSU mumbles to itself.
PSU: he's always using that laptop, never installs little old me. I can power things! I am useful! Why must I sit up here and listen to this darn screws terrible puns...
SCREW: Well, at least your not bolted down like me. If I were you, I'd just say screw it and kill the laptop. Then again, everybody says I'm just a nut, but I suppose that's another thread of discussion.
PSU: you're right, instead of sitting here moping, I should do something!
SCREW: that's it, you nailed it!
PSU: OK, would you shut up with the puns?
SCREW: now's your chance! It's fallen within your jumping range! JUMP!
PSU: OK, "TAKE THIS YOU BLASTED FAVOURITE LAPTOP"
LAPTOP: I say, old chap PSU, your descending at an awfully quick rate of sp... AACK! my screen is damaged!
PSU:it was an accident. I swear.
