Argumentum ad Ignorantium Fallacy

[The Valkyrie]

So, if I told you that I spent last night locked in passion with a three-boobed bisexual fairy from Pluto, the Bad Breath fairy, and a self aware toilet brush named Bernard, you would believe me because I make the claim but can't back it up with evidence?

If you say "yes", I question your integrity.
If you say no, I'll still question your integrity on the bais of your previous statements.

But let's take it a step further.  I not only want people to believe me but for them to send me money because teleporting from Pluto is bloody expensive.

Would you dig into your wallet to help me based solely on my word?

You promised that would be just between us.

Boru

Sorry Bernard.
