It's not the calories I would worry about, but the fat content. Especially factoring in all the dips. Seeing as a 10 box of nuggets comes with 4 dips, I am guessing this comes with a lot more.  They start at about 60 calories and 2g of fat (honey mustard), but some can go up to 170 cals and 18g of fat (ranch). Guess which one the hams will choose? Mcd's website claims a 40 pc nugget meal with ranch dip is 2670 calories, 142g of fat, 24g saturated (yikes!), 262g of carbs of which 77g is sugar, and 3890g of sodium. Thing is fatties will invariably ask for extra sauces so you can push all of these up a fair bit. Terrifying to think that some beast out there will demolish this on their own.
