Don’t forget to tune into CBS tonight as Senator John McCain comes crawling back to the Late Show with his tail between his legs for the first time since famously pissing off David Letterman last month.

Letterman had a cow after McCain skipped out on an appearance in favor of an interview with Katie Couric interview, joking that the Republican from Arizona left him feeling like an “ugly date.”

“I screwed up,” the GOP nominee for Commander-in-Chief tells the late night host during tonight’s return.
