The Late Show host Stephen Colbert talked about the upcoming presidential debate on Tuesday while encouraging viewers to fill out Donald Trump’s debate prep survey.

The first presidential debate is nearly here, and apparently republican presidential candidate Donald Trump still isn’t 100 percent sure as to what he should be saying during the debate.

The Late Show with Stephen Colbert is getting fired up about the first presidential debate, which will be taking place on Monday. The big reason they’re all so fired up is the fact that The Late Show will be airing live immediately following the debate, which means some interesting television for viewers.

During Tuesday night’s episode of The Late Show, Colbert talked about a new survey that Trump’s campaign staff is asking supporters to fill out. The survey is essentially asking supporters what Trump should talk about during the debate. You can watch Colbert’s reaction to the survey in the YouTube video below.

After looking over the Trump survey, Colbert had a great idea. During his opening monologue, the late night host asked all of his viewers to go online and fill out the survey. However, whenever the “other, please specify” option was available, Colbert wanted viewers to check that box and fill in what they want to hear Trump talk about.

Examples of Trump talking points could be about his tax returns or whether he’s really a billionaire or not. The options are endless, so hopefully Colbert can get enough viewers to actually fill out the survey with some hilarious responses.
