The Bluth family's country club holds annual bachelorette auctions to raise money for various causes. In 2003, it was the Save the Wetlands Bachelorette Auction. In 2004, it was to reseed the golf course greens.
Lindsay, who spent a miserable afternoon in the actual wetlands, was a complete mess and no one was bidding on her. Michael, proud of her effort, bid $1,000 to save her from embarrassment. Lucille gave Buster $10,000 to bid on her but he accidentally bid on Lucille Austero. ("Charity Drive")
At the 2004 auction, the proceeds were going to reseed the country club's golf course greens. Lucille Austero was once again up for auction and was bid on by Stan Sitwell until G.O.B. used the $10,000 his mother gave him to bid on her. A tranquilized Lindsay was going for only $10 and Tobias asked Michael to "borrow" some cash and excitedly blew all $5,000 on her. Michael then had to trade Stan Sitwell his newly acquired Corvette to bid on Sally Sitwell. ("Burning Love")
