"Buying the tails fresh"? (and Kuan, don't give me any crap about where I place the punctuation marks in relation to my quotation marks. Thank you.

If you go to a high quality fish market with good turnover, you can find fresh lobsters broken down into their component parts, but if you want REALLY fresh, buy a whole live lobster, harvest the tails yourself, and use the rest for other purposes.
Look for lobsters that are heavy for their size and lively, (especially when you poke their genitals, and I'm
not being funny).
