Collin McGrath has a very specific obsession. An obsession that so many men around his age have they even have their own name, The Bronies. Bronies are men fascinated with the show "My Little Pony: Friendship is Magic."

The Trinity University Junior found himself unexpectedly watching the show with his younger sister one day and connected with its theme of friendship. Collin was struggling at the time with figuring out where his place was in college.

Suddenly his fascination with the show took on a life of its own, when he started writing fan fiction. You can read a few of his more than 343,000 words here.

This story was recorded at Worth Repeating on December 12. The theme for the night was "Obsessions."
