Bo Jackson isn’t afraid to shell out for some good lemonade for a good cause.

The Auburn great was taking part in a pro-am event ahead of the PGA Tour Champions Regions Tradition in Birmingham when he stopped to visit a group of kids’ lemonade stand.

Jackson tells the kids that he’s willing to give them something if he likes the lemonade. He jokingly threatens to walk away if he’s not satisfied. After approving of the lemonade, Jackson places a $100 bill on the table, surprising the kids. The lemonade stand was raising money for the hospital Children’s of Alabama.

The PGA posted a video of Jackson’s generosity on Twitter:
