Best man speach at my brothers wedding

I would like some ideas of a speach for a wedding on Saturday October 17th 2022. My brothers name is Levi, Im dustin. hes 5 years younger then me, played football, not the smartest person, and we have argued our whole life. He is marrying his fiance Ashlynn. Some notable things. Hes short, thought he was going to make it to the NFL, has gained some weight in the past year, tore his ACL two different times playing football. Hes a salesman, has a bad temper. He played quarterback in highschool. he has red hair, and clear eyebrows. He headbutted a tree once and broke his tear duct and had to have surgery, he plays army men on the shitter. he is 27 years old. hes a lightweight drinking beer. the wedding venure was very expensive and her parents paid for it. There will be a donkey walking around serving beer at the wedding. Looking to have a funny speech written.
