Keith Olbermann, who’s been Tweeting all night mostly about baseball, took time to respond to Jimmy Kimmel‘s jokes about him at the White House Correspondents’ dinner. Kimmel joked, “I would like everyone to look under your seats. Under each one you will find a copy of Keith Olbermann’s resume.” Kimmel continued, “Is Keith here tonight? The limo wouldn’t pick him up? The thing about Keith is, he’s so likeable.”

Olbermann Tweeted:

Funny that Jimmy Kimmel ripped me after his people desperately wanted me to fly to LA to be on his show this past Wednesday #nerdprom

Olbermann added, “I’m not complaining about the Kimmel jokes – I’m fair game. I’m complaining about the revenge element. It reminds me of O’Reilly.”

Kimmel also took some shots at the cable networks during his set:

“Fox News is the grumpy old man of cable. Loud. Stubborn. Just had a mole removed. I would like to take a moment to salute the Fox mole. Were it not for his great sacrifice the world would never have known that the bathrooms at Fox were overdue for renovation.”

“As a result of all the success Fox News has had, MSNBC has moved a bit to the left of Hugo Chavez lately.”

“Every election year CNN comes up with new and amazing technology. And yet with all of the technical wizardry they still haven’t figured out a way to make James Carville look less like a hairless boiled cat.”
