First off, well done Virginia.
I tend to favor this second, more realistic (?) ending, because it incorporates two enjoyable facets; Lois with a haircut, and a dead Jimmy.

Hey, two for two in my book.

It's a good plot. Having the 'joke' blow up in Jimmy's face and there being serious and tragic consequences was a clever twist.

The other endings were okay, for what they were, but this one had a more logical feel to it.

Nicely done.

Tank (who had been working on his own story because he feared that no one would take up the challenge, but now the pressure is off... yeah)
