Stephen Colbert signs former President Clinton up for Twitter

The president agreed, even though Colbert acknowledged there was a potential stumbling block registering a Twitter handle for Clinton.

"Now, @PresidentClinton was taken. @WilliamJeffersonClinton was taken. But @PrezBillyJeff was available," Colbert said, earning a laugh from Clinton.

Clinton proceeded to dictate his inaugural tweet to the comedian.

By 9 a.m. Tuesday, Clinton's account had gained nearly 29,000 followers. It had also gained three new tweets:

"I'm Bill Clinton and I approve this tweet, because I wrote it, because, like I said, I'm Bill Clinton. #notColbertpretendingtobeme"

"Now that I'm no longer president I have been downgraded to Air Force Seven. #notColbertpretendingtobeme"

"Just picked up Ayn Rand. Mind = blown. Get to work, you moochers! #notColbertpretendingtobeme"
