Ackman, Icahn Showdown: Twitter Reaction

Missed the Big Fight? Watch It Now

In what may have been the most epic smackdown of rich guys to ever play out in public, Bill Ackman and Carl Icahn confronted each other on CNBC's "Fast Money Halftime Report" over dealings going back to 2003. (Read More: Ackman, Icahn Hurl Accusations, Insults.)

The clash was so mesmerizing that virtually all productivity on Wall Street stopped. Twitter lit up with reactions, and CNBC started trending.

Here are some of the best tweets:

"Wow. Real Housewives of Wall Street." @Ted_Newton

"Would like to see claymation death match reenactment" @JackAttax2

"Joe Peschi will play Icahn; a peroxided Jim Caviezel will be Ackman" @zerohedge

#RumbleOfTheHedgies @SweetStocks

"I think Carl just needs a HUG!" @EdwardBHall

"Buffett was watching from the bath tub." @ReformedBroker

"and the trading floor goes "WOOOOAAAHHH" @AnthonyQuintano

"How does the saying go? Men will be boys?" @CNNNYSE

"Now upgraded to 'Fight of the Century'." @NYTFridge

"Going long $HLF and buying Schmuck Insurance just in case!!! :)" @SconsetCapital

I also asked people on Twitter to choose a winner: #TeamAckman or #TeamIcahn. The early tallying has Ackman beating Icahn by a three to one margin, but suddenly #TeamWapner is making a strong run. Stay tuned.
