I remember this. My Mother recorded this episode while I was in preschool.

Wait a minute. The $16,000 mark isn't lit up properly, and even the $4,000 mark isn't turned off when he loses, there's a little mechanical problem inside that game and he doubles the money in order. There's a mistake in their part. I guess Bob Barker should've give John $16,000 in cash! (If you think I'm wrong in this comment, put some replies down below and let me know about this.)

The missing part of the show saw Jennifer win a $1078 Outdoor Porch Swing as the first IUFB, and played Lucky Seven for a $21532 Pontiac Grand Am and lost(she guessed $22670). John's IUFB was a $1020 wall clock.
