1. Bring to work, put pen on keyboard. Somehow get a colleague
to 'accidentally' close your laptop forcefully.
2. Open laptop, emit sounds depicting dismay and surprise, then
offer to be a 'pal' by asking only for half the amount needed to
fix damage.
Let me know how you get on. 
OR...
Carry laptop in laptop bag, do not use shoulder strap. Stand behind
a rich-looking executive, and then make him/her accidentally bump
into you thereby causing your precious laptop to fall onto the
floor. (you might want to put in a shit harddisk before doing
this)
Repeat step 2, above.
