Jon Stewart mocked President Obama's botched healthcare rollout during his show on Thursday night.
"Fully functioning by November, but, as of now for some reason, the site continues to give people hepatitis. We don't know why," Steward joked.
The comedian needled Obama for his statement Thursday that he never said he would be a perfect president.
"I think when you campaigned you were all 'Yes we can,' " Stewart said. "I don't remember the other slogan you had, 'Pobody’s Nerfect.' "
