A cowboy goes to the dentist....sits down in the chair and the dentist says "Cowboy...I need to give you some novicane to take out this tooth of yours"
Cowboy says"I don't need any stinking novicane...I'm a cowboy, and I've felt worse pain than having a tooth pulled"
Dentist says" Oh yeah...tell me about it"
Cowboy says "Well...SECOND worse pain I ever felt was when I was riding my horse along a trail and I had to take a dump...I hopped off my horse and squatted down and leaned up against a tree...and wouldn't you know it...there was a bear trap chained to the tree and it clamped onto my balls. It really hurt"
Dentist says" If that was the second worse pain....what was the first?"
Cowboy says: "First worse pain was when I started to run, and I ran out of chain".
