aka Papa Bird
Stephen's pet name for Bill O'Reilly.
Many liberals have tried to drive a wedge between Papa Bear and Dr. Stephen Colbert by claiming that since Dr. Colbert has correctly called out bears for what they truly are, this is indicative of Stephen's real feelings for Mr. O'Reilly. Hence, these liberals propose there is some implied grisly, or, if you like, repellent correlation between "Papa Bear" and bears.
It should be noted that most/all liberals have an extremely difficult time of not ruining things, such as America and the free market, so this charge of insincerity or mockery against Stephen towards O'Reilly is really a reflection of their hate for America.
The Goldilocks Investigation
In the famous Goldilocks investigation of the suspected bearorist training facility, sworn testimony from Goldilocks described Papa Bear in terms of "too hot" and "too hard"  as if those could be misconstrued as bad qualities.
