Sometimes I'm just that thick

As some of you have been oh so lucky to find out, I can be pretty thick sometimes. In fact, I know that I can be downright dense.... and here's an example from everyday life to show that, basically, I'm just a moron:

Scene: A car and a truck travelling in opposite directions. They stop, and the drivers lean out their respective windows.

Other Driver: Hey... how do you like your coffee?
Me: Meh, whatever... doesn't matter.
Other Driver: Would you take a double-double?
Me: Well, I'd prefer regular.
Other Driver: But you'd drink a double-double?
Me: Actually, I'd prefer regular.
Other Driver: Okay, I have a double-double right here. Nobody wants it. Will you drink it?
Me: OH! Yes... yes I will. Thanks.
