Superman Fan

"I know you like comic books. So what's your favorite one that you keep telling me about?" Karyn asked Jon. "Well, Superman, of course. Isn't it kind of obvious?" he asked, gesturing around his room. Karyn looked around. She didn't even notice until Jon pointed it out. All the posters in his room, which used to be either sports or movie posters, were now Superman posters. The wallpaper was Superman-themed. His bed was also Superman-themed, as were his window curtains. And everything else was either colored red or blue, or both. And on his shelf were dozens (maybe even hundreds) of Superman comic books. Jon was obviously a die hard Superman fan.
