the definition of feghoot is pretty much as given for powfag, as suggested in that thread.

hesitantly (with TEd in the neighborhood), I present a feghoot which is attributed to Isaac Asimov:

Monty Stein, in the year 3047, committed 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 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."
