Nothing worse than the pseudo-educated flapping their jaws.
The exception proves OUT the rule.

Jim - Learned that at hard-knock school. *1st grade.


Help me out here Jim. Im not sure what you mean by .......proves OUT
the rule......

Do you mean it .... supports the rule?
or
does not support the rule?

I dont know what you mean by proves out. I assum that its a quirk to
your local dialect. Are you from texas or the south? or have parents
from that area. Im interested in the origin your word choice.
