Rick Perry offers 'Top 10' excuses on 'Late Show with David Letterman'

rick-perry-cbs.jpg Rick Perry has had a rough campaign for the Republican presidential nomination. After starting off hot out of the gate, he's stumbled and gaffed his way into a deep underdog position. And things got worse Wednesday (Nov. 9) when he forgot his own talking points during a debate.

Well, rather than hide from his mistake, he decided to go on " The Late Show with David Letterman" to offer his "Top 10" excuses for the foul up.

Here's what Perry had to say:
