I don't know. Had he not been banned, here are some other topics he may have come up with:
* Instead of having the showcase showdown as is, have the three contestants in front of computers with browsers open to random.org. Each contestant uses that website to pick two numbers 1-20; whoever has the highest total goes to the showcase.
* Double Prices has become too easy and should be Triple Prices.
* The showcase winner is done by secret ballot; whomever the audience likes more takes their showcase. If the vote is within 2.50%, the winner gets both showcases.
And finally...
* Bob Barker should be replaced by Dave Price.
See...this is what we could have had had he not been banned
