Expect to feel the wrath of Jon Stewart if you trash one of his fellow Comedy Central hosts.

Many pundits and politicians -- most of them conservative -- criticized Stephen Colbert for testifying in character Friday before a House immigration subcommittee after being invited by Rep. Zoe Lofgren (D-CA). Stewart came to Colbert's defense Monday.

Lofgren asked Colbert to tell the subcommittee about his experience working for a day in a job typically done by undocumented workers.
