Put your laptop and couch into Family Storage. Invite a couple friends over (3-5), invite them inside and eventually one or two of them will pull a laptop out.

As soon as it is placed on the kitchen table (I got a big table) press Start and select the laptop any sell it! Cha Ching!

Whats great is that sim will usually pull out another laptop and just keep selling them.

I banked $40,000 just for hanging out.
