Let sleeping dogs lie.
Kansas City Chiefs running back Jamaal Charles is no scaredy-cat, but he does confess to having a fear of canines.
He remembers getting bit as a kid while playing basketball.
"I'm still afraid of the big ones," Charles says.
He also recounts playing quarterback in Pop Warner, which teammate violates the team hot tub code and who has the worst feet in the NFL.
Now, that's something even we're scared of.
