Would You...

[DeathsHand]

I'm not someone who's really capable of impressing anybody with knowledge, nor am I someone who's particularly impressed by knowledge, so I'm usually fine admitting that I don't know.

Or sometimes I make up a lie that's clearly a lie for humor's sake.
And sometimes I substitute "I don't know" with "I don't really care about that", because that's usually the case...

And other times I do what Bube said...
And sometimes I just pretend like I'm zoning out and didn't hear the question...
