A 32-year-old man nicknamed “Mr. McDonald’s” has been eating at the world’s most popular fast food chain every other day for the past two decades, and has invested a small fortune in McDonald’s-related clothes and memorabilia.

David Geyer, a gardener from Bergheim, Germany, first ate at a McDonald’s fast food restaurant in 1997, and the moment he took a bite of that very first burger, he knew that the iconic fast food brand would become a part of his life forever. He came back for more every chance he got, but he realized just how passionate he was about McDonald’s when he got his first job and started spending more time at the local McD’s than he did at his mother’s dining table. His love for the fast food chain has since transcended food, as he has since gotten permanent McDonald’s tattoos and invested in burger-themed clothing and memorabilia as well.
