Monstrous Wendy's burger returns, daring customers to devour 9 patties in 9 minutes

A long-extinct Wendy's burger has returned from the fast-food grave , packing a whopping 3,000 calories and costing nearly $30.

A franchise in Edmund, Oklahoma, was recently spotted with a sign out front advertising the T-Rex burger challenge, which awards participants who finish the towering nine-patty cheeseburger with all the fixings in nine minutes with a T-shirt and a special prize, Allrecipes reported .

The burger costs $29.99, according to the sign, which was posted on Reddit in early September.

"Think you can take down the T-Rex? Prove it," it boasts.
