I took a closer look last night after I posted. The numbering for eight and nine are screwy - probably because of Murder -- Eyes Only and Nine Dragons being split into 2 parts. It probably has to do with the syndication and/or the schedule set up. These networks have the shows slated for one-hour slots. During the original run, CBS had the flexibility to expand the slot into two hours.

Also of note on Season 5 - Pig In A Blanket is missing. Considering some of the subject matter, I'm not surprised by some of the skips. While others have me scratching my head.

Compare H&I's list with Mr. Mike's Comprehensive Index and you'll really see what's missing.
