Believe this is Burke, Andrew Vachss’ character.
NDP 6 - Age and sex: early 30’s; male. Subject is a former insurance investigator suffering from amnesia and short-term memory loss. Seemingly easily manipulated by people who take advantage of his mental disability. Prone to writing notes and tattooing messages on himself to remember things. Obsessed with finding out who was behind the death of his wife.

And this is the guy from Memento, Leonard.
No, but I’ll add a little more to the description.
NDP 5 - Age and sex: about 35; male. Subject is employed as a law enforcement officer in Los Angeles, California. Hot-tempered and prone to physical violence (especially against suspects accused of abusing women). “End justifies means” type who disregards rules and laws in the course of doing his job. Subject is single but has a relationship with a sex industry worker. On medical leave to recuperate from wounds suffered when internal investigation into department corruption led to gunfight.
You got NDP 6. It is Leonard Shelby from Memento.
At first I thought you might be speaking of Samantha Stevens, although Maurice could hardly be said to be often in her company. Then I realized that I’d read about the movie version giving a meatier role to the dad. So is it the Nicole Kidman character from last year’s Bewitched?
The original “Bewitched” series drew heavily from the 1942 film, I Married a Witch. I think the description is referring to Veronica Lake’s character in the movie.
No, it was Lieutenant Arthur Tragg (Ray Collins) from Perry Mason. I’ve never heard of Lenny Briscoe.
The maid from The Brady Bunch.

Fred Madison from Lost Highway? Is that too obscure?
Correctamundo.
Yes.
Ah, yes, now I recall. Thanks for not making it the Will Ferrell vehicle. Frederic March as the warlock daddy.
Nobody got these:
26. Alfred E. Neuman
28. Dr. Juliet Burber (9 Chickweed Lane)
30. Alice Terwilliger (from the “Surreal” thread in MPSIMS in the SDMB)
A few more:
36. Age & sex: Unknown, but estimated about 35; male.
Subject employed as family retainer. Not given to much speech; deep bass voice. Rather frightening eyes. Very tall man, but well-dressed and well-mannered. Expresses disdain with low-pitched groan.
37. Age undetermined; sex apparently male.
Subject lives in watery environment. Wide eyes, yellow color, snag-toothed grin. Always wears odd-shaped shirt, slacks, necktie.
38. Age & sex: 45; male.
Subject is naval officer, commander of small fighting vessel. Has very liberal attitude about personnel under his command, concerning regulations. Subject’s immediate superior apparently makes constant efforts to remove subject from command, but is thwarted because of subject’s military-based knowledge of the region, which would work against superior officer in any administrative proceedings.
39. Age & sex: About 45; male.
Subject has speech defect with “r” and “l.” Claims constant obstacles in his effort to pursue hunting, including exploding firearms, misjudged space under feet, and uncooperative prey. Speech therapy recommended, along with scalp treatment and training in handling firearms.
40.
Age & sex: 17; female.
Subject interviewed in palatial mansion. Severe vanity obvious in speech, demeanor, and apperance–expensive clothing and jewelry (in keeping with ambience of fancy house). According to her accounts, household staff has unexplainable habits of leaving throw rugs in wrong places; leaving rare and valuable crockery where vulnerable to theft or damage; leaving various other items in proximity where slight damage to one can cause serious damage to another, which often happens when subject’s boyfriend–a total klutz–visits, as he often does.
The Naval Officer is McCale, from the show McCale’s Navy

Two of mine haven’t been answered so I’ll again add to their descriptions.
NDP 4 - Age, sex, and residence: approximately 30; female; Boston, MA. Physical traits: blonde hair, tall, thin.

Single but has a relationship with former sex industry worker.
Diane Chambers, Cheers.
You are … correct!
Correct, except the name is McHale. 
This was from awhile back but I’ll answer it now.
Tom Green’s character (don’t recall his name) from Freddy Got Fingered.
And, just to see if anybody’s still interested, here’s another one of mine.
NDP 7 - Age and sex: 4; male. Subject is from Mexico and about 6’6". Formerly an industrial laborer but currently employed in the field of package/freight delivery. Kleptomaniac who smokes and excessively consumes alcohol; regarded by fellow employees as selfish, amoral, and defensive. Has latent desire to sing folk songs.
