Here's a punderful thought ...
If you can't stand the sight of someone is that "facial discrimination?"
Certainly that would depend on how you define the root word discriminate. I agree with Isaac Asimov*, puns are one of the highest orders of humor. And the worse they are, the better they are (a punster will understand that). Sadly, almost everything that enters my head becomes a pun and it often drives me to distraction. My friends have begun to treat this condition with ignore-ance, but will often let a sly smile slip by in acknowledgement.
*Here's a good one by Asimov I found on the Web while looking for the definition of feghoot:
Monty Stein, in the year 3047, committed quite a heist and made off with quite a tidy sum. He was eventually caught, and the judge sentenced him to seven years imprisonment. However, the night before his impending incarceration, he calmly set his time machine for seven years and one day, and stepped through.
When he emerged in 3054, there was quite an uproar. Prosecution maintained that Monty Stein never actually served the sentence, since effectively no time passed for him. Defense stated that the effect was basically the same, since he lost seven years of living in society, or something to that effect. Both sides called each other names (as lawyers are wont to do).
Eventually, Stein was set free. Some say that the judge succumbed to peer pressure; others said that he simply couldn't resist the temptation. For his decision, in full, was:
"A niche in time saves Stein."
