George Costanza Singing About McDonald’s McDLT Will Make Your Day [VIDEO]

What if I told you that Jason Alexander (aka George Costanza) used to have hair and sing about McDonald's burgers in the mid 1980s?

I stumbled upon this 1985 commercial about McDonald's McDLT by accident and my curiosity got the best of me. I had to know what a McDLT was. Turns out that's just a fancy name for a burger with lettuce and tomato on it (hence, the "LT"). However, seeing Costanza sing and dance like it's the Summer of George made the trip totally worth it. Man, the 80s were a magical time!
