Also, I'm not really sure that .Org is well suited for humour as a general rule, so you might choose .Net.
Frankly, given what you state directly and what is implied (including that the .Com is already taken) I don't think the choice is going to be significant to the outcome of "ranking".
Use the .net if the .Com is parked.
In terms of rankings for a subject internationally,
.net if you cannot think up a good name, .org is globally recognised as not-for-profit/charity, well, ought to be anyway!
