Project Quantum Leap's present date is given as September 18, 1999, exactly eight years after this episode aired.
Ziggy tells Sam that Al has saved Sam's life 23 times. Up to now, Sam has leaped at least 54 times. That means Al has saved Sam at most 40% of his leaps.
Al was born on June 15, 1934.
The Project Quantum Leap computer, Ziggy, was referred to as "he," with Al even once suggesting that "he" needed a "girl computer" next to "him," until this episode where the workings of Project Quantum Leap are seen in detail. Ziggy turned out to be a computer with a very flirtatious female personality, and thereafter was always referred to as "she."
Although he was mentioned in most episodes in the interim, this marks Gooshie's first appearance since the series' pilot Genesis: Part 1 - September 13, 1956 (1989).
