I have become such a fan of this show, I can’t believe it. From the opening theme song to the always bizarre ending, I so enjoy it.
It has created a new appreciation of Stephen Colbert. On the Daily Show and his own show I got the feeling he was a droll one-trick pony. I stand corrected.
There is a surprising depth (although wonderfully hidden in fun dumb jokes) to this show that I find delightful.
You will be assimilated! 
HB is one of the best shows Adult Swim has put out. I’m glad to see there are so many fans around, I thought for a while I was the only one enjoying it and was expecting it to get cancelled.
I love the way they incorporate old Hanna Barbera cartoon characters (whom I grew up on), and I love the quick little one shot jokes you might miss if you’re not paying attention, like the episode where Harvey and Reducto are carpooling to work and Reducto says something to the effect of, “Besides, what harm can one person do to the environment?” while a limo with GW Bush drives past in the background.
The Jetsons episode alone is enough to make it one of my all time favorites, and Mentok the Mind Taker makes every episode he’s in even better
My favorite episode is now the one introducing Bird Girl.
“Daddy!”
Morocco Mole’s case spoofing the shaky evidence used against suspects of The War Against Terror (TWAT) (cameo of Bush in his Mission Accomplished uniform)
And the ending where they made a hilarious spoof of the old Batman TV show and the Batman movies.
