Well, a Sorlock's wild magic back story might start with a family curse or a long - forgotten pact. Their ancestors could have been involved in something that led to this wild magic connection. For example, a sorcerer in their bloodline made a deal with a fey being associated with wild magic. As a result, generations later, they inherit this wild magic - influenced power. It could also be that they were born during a rare celestial event that disrupted the normal flow of magic, causing the wild magic to seep into their being.
Perhaps some stories involve the challenges faced at the first tee. For example, a golfer might have been really nervous and had to overcome that to make a good shot. There could also be stories about the beautiful scenery around the first tee that inspired players. Another aspect could be the friendly competition that starts right at the first tee, with players joking around yet still being competitive.
In 'Pulp Fiction', Jules is a character. Maybe a tee shirt could be related in that there could be a tee shirt with Jules' image on it, or perhaps Jules was wearing a particular tee shirt in the movie that became iconic in some way.
