Witzelsucht is a mental disorder that causes the sufferer to compulsively make inappropriate jokes or puns -- all the time. The condition is generally a result of a stroke in (or an injury to) the orbitofrontal region on the right side of the brain.

I'm sorry it took so long but... "Yes, i think we can all claim dat we have dis ability."
