J.J. Watt surprised his fourth grade teacher in Pewaukee, Wisconsin when he turned up with cake and presents Monday.
In the visit broadcast on Facebook Live, Watt said the soon-to-be retired Mrs. Keefe was one his "favorite teachers of all time."
"(She) happens to be the one who told me I could play for the Wisconsin Badgers, told me I could play in the NFL," Watt said. "She is one of the biggest inspirations for me. She's unbelievable and she's retiring this year after 41 years."
He brought her a retirement cake, a pair of his J.J. Watt shoes, and an invitation to this Charity softball game with her family on May 13.
Mrs. Keefe then introduced Watt to her class with the same lesson for her students.
"Look where he is now," she told her class. "Whatever you want to do, you can do it."
