What might be a lot of money still might not be enough to buy you.
For some people, a lot of money is $100. Others $1000. Even though I'm certainly not wealthy, neither of these amounts would make me jump up and down screaming if I won them in a bet, or whatever. This is why I have trouble at the horse track. I can't afford to bet the amount it takes to get the juices flowing for me. So, what is a lot of money to me? $500k is a decent sum, but anything under about $10M is money you could easily spend up. But, I like the number $10M because I could manage that and live comfortably for the rest of my days, methinks.
As for buying me, it would take quite a lot guaranteed to get me to commit most crimes and several sex acts, but I'm sure there's a number out there somewhere.

And, don't bother trying to convince me that you can't be bought. There IS a number, however high.
