Craig Ferguson: 'Denver Makes Me Poop Funny' (VIDEO)

Craig Ferguson, the host of the Late, Late Show on CBS, gave Denver a shout out on his show Friday night, but he may have divulged a bit too much information about how the altitude affects his bodily functions. "It's very high up, there. It's very hard to breathe, and it makes me poop funny," Ferguson told his audience.

Despite these complications, Ferguson was in town for a book signing at the Tatter Cover's LoDo location on Saturday for his new autobiography, "American On Purpose." Check out the clip from Friday's show here:
