^ That's all accurate. From the episode summary for May 4, 2001 on Scorpz's site:
"According to Chistopher Bogart (who was at the taping of this show), atthe 6th IUFB Bob had the price of the first showcase and not the price of the Executive Desk Set. So, when Bob revealed the price of the 6th IUFB, he said "Seventeen". He stopped himself, realising the mistake. They then stopped taping and got the real price. Everyone in the studio knew what the wrong price was for. Cliffton bid $17,000 on his showcase and won. Why Alma passed that showcase I have no idea. Don't believe it? You can clearly hear it, thanks to lousy editing. Bob says "Ssss... 805".
Clifton ended up being only $390 off and won.
