The radio broadcast of the horse race is called by Jim Healy, who, while not credited for the part, does actually announce “this is Jim Healy.” Mr. Healy was a well known radio and television sports personality in the Los Angeles area for 30+ years. Submitted by D. A. Supernaw, 2/24/2005.

Burger presented a list of serial numbers of the $20 bills in the theft case. On the stand he had the detective Sgt. McClanahan & Rodney Banks compare the last number on the list to the $20 he handed them. If you look closely you’ll notice someone has pasted on 2 new serial numbers on the $20 bill .... K 0 0 4 9 _ _ _ _ A. The line of numbers on those 2 places are lighter paper than the rest of the bill. Submitted by Daniel Jones, 12/27/2007.
+ The serial numbers on the bill are K00460975A. They definitely appear to have been pasted on. Both numbers show the “border lines” one would expect from the thickness of the stick-on. Quick picture here (use browser’s back function to return). Submitted by daveb, 1/11/2011.
+ Had they wished to be a little more authentic, the writer and the props crew could have begun the serial number with the letter "L" to match the Federal Reserve District bank which issued the bill. The district seal can be seen in the close-up, showing the letter "L" corresponding to the San Francisco Federal Reserve district. If you could read the writing in the round seal surrounding the "L," it would identify the San Francisco Federal Reserve bank. The number "12" seen in four corners of the inner space also refer to San Francisco ("L" is the 12th letter). Letter "K" corresponds to the Dallas district (which should likewise show "K" in the district seal, and the number "11" in its corners). The redesign in 1996 changed some of these features for newer bills. Submitted by alan_sings, 1/1/2012.

Sightings: At the racetrack, Distinguished Gentleman #1 might walk behind the angry Marvin Fremont as he yells at Perry. Then he walks a few seconds later behind Sgt. McClanahan, and then again (but this time with an escort) just before leaves the confrontation. But he definitely shows up at trial, along with Quiet Old Man #1. Submitted by gracenote, 3/5/2011.

Robert Wegner looks only a bit less scowling at his promotion from his usual bailiff to Burger's No. 2 in this episode. Submitted by FredK 3Feb12.

Hard to believe, but the beautiful Joyce Bulifant later played Murray Slaughter’s wife in the Mary Tyler Moore Show. Submitted by cgraul, 7/12/2011.

Halstead and Paul have a rare extended conversation in Della’s office. Note the oddly empty bookcase we usually see only in quick glimpses when Della enters and exits Mason’s apartment. Submitted by cgraul, 10/13/2011.

Hamilton Burger delivers one of the few opening statements in this show (this might be the only one). This is rare because of (a) time, (b) money to pay more extras, and (c) the show (and books) rarely used juries, as Perry usually revealed the murderer at a preliminary hearing (also called “probable cause” hearing). Submitted by cgraul, 10/13/2011.

Nancy Banks' beautiful soft-top convertible is a 1958 Ford Fairlane 500 Sunliner. She has the (white?) top down. We get a good look at the car as Nancy arrives at the Valley Trout Farm ("Tackle & Bait Furnished - Open 10AM to 8PM Daily").

• This is the second of two consecutive episodes in which a Blonde Bombshell driving a flashy convertible ditches her tail in L.A. (the tail, this time, being Perry)!
• This is also the second Mason episode in which a Beautiful Blonde is the driver of a '58 Fairlane convertible (1st was ep#155).
