Why do we pull funny faces when performing delicate tasks?

I think that is just you :P

I do this. Don’t know why.

Concentration = tension. Tension = tightened muscles. Tightened muscles = involuntary funny faces.

Imagine what a surgeon must look like

LOL! Yes, what @elbanditoroso said!

I read somewhere that sticking out one’s tongue is a holdover from infancy. Infants stick out their tongues when they’re being fed something they don’t like. So when older children or adults stick out their tongues during a difficult task, it can be a visual cue that they’ve had enough fo that particular task.
