Gardener Danny Haataja has grown some oddly shaped vegetables before, but nothing like the potato that he will put on eBay for $100 on Thursday.

"I've never grown a potato that looks like a duck before," 52-year-old Haataja said. "I wiped the dirt off, and it even has an eye in the right spot."

Haataja, of Menahga, Minn., plucked the Yellow Finn spud from his home garden and was ready to eat it, but his nephew suggested they sell it.

After all, there is a market for this kind of thing. The duck-potato will join a heart-shaped potato (starting bid $1.99) and a "happy face on toasted toast croissant" ($50) currently on sale on eBay.

People also like to sell their carbs. A "Virgin Mary" toast sold for $28,000 in 2004, according to the BBC.

Haataja said this is the first time in 40 years that he has grown a sprout worthy of being sold, and it will likely be the last.

"I doubt this will ever happen again, actually," he said. "This is just a fun thing. It's entertaining . I've seen some good ones on the 'Ellen Show' before."
