It was one of the two final episodes of the season; but I forget which one. Annie is out in California shooting the soap opera in which she has just landed a role. Playing a cop in a scene in an emergency room, she says:

Well, sir, I was working the 8 to 4 at the 37th, when a 413 came in from the 7-11 on 14th and 3rd; the 5150 proceeded to call 911 at approximately 4:23 pm on 5/5/97.
