It is hard to drink a gallon of milk in one sitting, and harder if it is in a very short time! I know Joey Chestnut has the record in 41 seconds but I am happy to have conquered a personal best of 2 minutes :) Please check my video out! thank you so much! Alex.

Alas, only one photo was found for this burger challenge. I also tried to get to their site, and it was gone, so not even sure if they're still in business or not. Can anyone near Ferntree Gully, Victoria confirm this? Would be a shame to see this fine burger challenge disappear! The Challenge, eat the burger in less than an hour to get your name on the honor board. No prizes though...

Big Heavenly Burger Challenge, Captain America's Hamburger Heaven. Ferntree Gully, VIC, AU
A double burger weighing 1 kilogram( equal to 2.20 pounds) served with 600 grams (equal to 1.32 pounds) of potato chips. Clean the plate in less than an hour to have your name on the honour board. World record is just over 8 minutes, beat that and the meal is free. I didn't quite make it in 8 min, more like 30min 54seconds. And I felt 10 kilos heavier afterwards.

Not sure where this one is in Colorado, but looks like this guy nails it! It's 12 hot hot wings in 6 minutes or less.... shame the vid wasn't better quality, I reckon he looked like he was struggling near the end there...

I went on a trip and while I was there a buddy decided to take the Hot Wing challange and see if he could eat 12 extremely hot wings in under 6 minutes. The price a t-shirt and his picture on the wall

Only one pic, but a worthy burger no doubt!

You can't get much more Aussie than "Weet-Bix", a breakfast cereal that's been around in Australia for years. So to celebrate Australia Day (January 26), I thought I should let everyone know about this great Aussie food challenge, "The Weet-Bix Challenge". The Challenge: To eat a dry Weet-Bix in 60 seconds or less. Much like the "Saltine Challenge" (more on that later), this Wheat-based biscuit cereal is VERY dry, and eating it without the assistance of milk, water, or any other fluid in 60 seconds is pretty much close to impossible. Enjoy the hilarity that is "The Weet-Bix Challenge", and Happy Australia Day everyone!
