Well, one Cardinals fan showed his love by having a mural of Busch Stadium painted on his gut.
The St. Louis Post-Dispatch said Jeff Rearden got it painted on at a bar before the game and proudly displayed it for the world to see.
"I just let the artist do whatever she wanted. And she painted this," he said.
Rearden was more than happy to oblige other fans with photographs. But here's hoping nobody asked to see the flagpole.
Why you’d want that picture on your phone is beyond me. pic.twitter.com/Pzh2Xq1B4C
