Poll: What type of thumb do you have?

[Thedayrecker]

My thumb is straight, up to the top where it curves just enough to be declared "In between".

My left hand is the straight one and my right is the Hitchhiker's & double jointed.

Straight... I don't think you can, technically speaking be 'in between' either your two joints bend back a bit further or they don't. That's all there is to it.
