Alex Karras is known for many things. Played football, was a sportscaster, wrestled, and starred in Webster as George. Oh yeah, he also did a Transformers Christmas commercial where he nagged your parents to buy them ASAP.
Honestly as nice as Alex seemed in life, he strikes me as that uncle who at the family Christmas dinner eats the entire cheese ball before clogging the toilet. He later say's something about laying the yule log. I know a lot about that uncle.
