I thought it might be helpful to have a ranking of the ADAs from 'Law and Order' in ascending order of hotness.
1) Richard Brooks as Paul Robinette. A dude, so last place on that alone.
2) Angie Harmon as Abbie Carmichael. Meh.
3) Jill Hennessy as Claire Kincaid. Super hot, but points were deducted owing to membership in the itty bitty titty committee.
4) Annie Parisse as Alexandra Borgia. May have been ranked higher, but suffered from George Lazenby syndrome.
5) Elisabeth Rohm as Serena Southerlyn. Ranked relatively high owing to revelation that her character was a (hot) lesbian. The possibility of an ADA three-way is hard to ignore.
6) Carey Lowell as Jamie Ross. Growl! She's so hot that we're going to forgo any jokes about her husband's proclivity for hamster stuffing*.
