Maher is a very very very bad rip off of George Carlin. A total Carlin wannabe. Thing is Carlin never would have told a joke like that because it’s so stupid and unfunny.
Carlin was funnier (by degrees maybe) because he knew the difference between funny and just rude. Maher’s lib audience prefers rude over funny. Quoting Dr. Strange “liberalism is a mental disorder”.
