One of their skits included a little diddy on the president's troubled online health care exchange.
The country stars led into the bit with Paisley telling Underwood he needs to see a doctor.
"Hey do you have that Obamacare?" Underwood asks Paisley. "It's great. I started signing up last Thursday, and I'm almost done."
The two then attempt to sign up, which launches them into this song set to the tune of George Strait's Amarillo by Morning:
"Obamacare by morning.
Why is this taking so long?
I am going to wind up with hemorrhoids if I sit here till dawn
We'll have cataracts and dementia. Oh this is getting on my last nerves
Obamacare by morning, over six people served."
It's one thing to make a joke about the health care rollout(it has been ridiculous), it's another to make the joke in front of a crowd full of conservatives. Added fuel to the fire.
