Hypothetical #1

What's more wrong:

- Me putting a posting on Craigslist saying that I would give one dude a handjob for a million dollars, and then not following through.

or

- Me putting a posting on Craigslit saying that I would give one dude a handjob for a million dollars, following through, and then the dude not giving me a million dollars.

Let's assume in both cases that there's no way I'm capable of giving a million dollar handjob.
