The answer is:
The correct question is...
How many FREE milkshakes did my husband manage to squeeze out of Whataburger yesterday?
He took himself and three kids (in their pajamas) to Whataburger for a free breakfast milkshake. He then fed our kids and two extras Whataburger for lunch where he snagged six more free milkshakes. He printed three free milkshake coupons and gave them to others to use. And then finished the day with a round of free milkshakes to drink with dinner!
Stand amazed, people, stand amazed!
And, don't be surprised next Christmas when Whataburger withdraws their 12 days of Whataburger promotion!
