Psycho Needs A Lawnmower

Original Ad: Selling a lawnmower. $50. Works great.

Me to Dave ******
Hey, I'd like to take the lawnmower off of your hands. But can I have it for $23.19? That's all I managed to find in my change jar.

Dave ****** to Me
Hey, I'm not trying to start a charity, I'm trying to sell a lawnmower. You're going to have to buy one elsewhere.

Me to Dave ******
No need to be rude. But no need to worry about money, either. A kid just rode by my house on his tricycle. I think he was headed for an ice cream truck or something. I went up and punted that sucker off of his three-wheeled piece of crap and took his ice cream money. I now have $28.19. That good enough for you?

Dave ****** to Me
I hope this is some kind of a joke. Anyway, I already sold the lawnmower, so you're going to have to buy one somewhere else.

Me to Dave ******
$28.19 isn't enough for you, I get it. You Daves really love your money, don't you?
So I found some kids running a lemonade stand. I held them up with an Airsoft machine gun. They though it was the real thing. Haha!
Now I've got $42.65. Is that enough?

Dave ****** to Me
The lawnmower is SOLD.

Me to Dave ******
I just stole the tip jar from a Mcdonald's.
$49.52?

Dave ****** to Me
How many times do I have to say it? The lawnmower is no longer for sale. And if this isn't some kind of joke, you could get arrested for what you've done.

Me to Dave ******
Man, Dave, you drive a hard bargain. But I just went up to some random person on the street and beat the crap out of them. I don't know if it was a boy or a girl because they were bald. Also, it was hard to beat them up with the tubes and the wheelchair in the way.
I have $72 even now. That's more than you were originally asking. Is this finally enough?
