<human>: Can you provide a brief overview of the text?

All in the title.

Not my story, but my Dad's:

So my dad had just gotten sinus surgery, which anybody who's gotten it before will tell you hurts like a bitch. So, his doctor prescribed him some pretty strong pain pills. He's into restoring old muscle cars as a hobby, so he's often on the vehicle section of Ebay.

Not being able to go to work, he pulled out his computer and started surfing Ebay for cool things to look at. Of course, a WWII Helicopter and a Korean War tank were on sale. The helicopter got pricey quickly, so he abandoned that, but was still bidding on the tank. He got up to $8,000 before my Mother noticed what he was doing and stopped him.

But the best part is,in his super-highness, he somehow had the wisdom to call his friend who runs a scrapyard, and ask him how much a tank would be worth, and it was around $10,000 if I recall correctly. 

So my Dad almost bought us a tank, which would have been awesome, but it ended up selling for way more than it was worth in scrap, and my Mom veto'd any attempts to bid higher.
<bot>: Dad got high on pain pills after painful surgery, and I almost was going to get a tank as my first car.
