With a guitar and laptop in hand, Paisley and Underwood sang "Obamacare in the morning" -- to the tune of George Strait’s “Amarillo By Morning" -- while Underwood attempted to register for healthcare.
"Hey do you have that Obamacare?" Underwood asked Paisley. "It's great. I started signing up last Thursday, and I'm almost done."
“Obamacare by morning, why’s this taking so long? I’m going to wind up with hemorrhoids if I sit here til dawn," they crooned. "We’ll have cataracts and dementia, Oh this is getting on my last nerve. Obamacare by morning ... over six people served."
