Okay, the armadillo technically can't shoot you back - but its tough shell can cause the bullet to ricochet right back at you.
That's what happened to a Texas man who discovered an armadillo outside his house early one morning and decided to "shoo" it away with his .38 revolver:
"His wife was in the house. He went outside and took his .38 revolver and shot three times at the armadillo," Rowe said.
The animal's hard shell deflected at least one of three bullets, which then struck the man's jaw, he said.
