“Democrats and Republicans are interesting because Republicans really laugh at themselves more. Like when Bush came on, it was, ‘We want to do a skit, we’re kind of making fun of… — ‘Yeah, go ahead!'” said Leno on NBC’s “Press Pass” with David Gregory, who appeared on Leno’s show earlier in April.

Former Vice President Al Gore wasn’t quite as easy going on camera as former President Bush, according to Leno.

“We went up to Al Gore, ‘can we do this skit?’ — ‘Hang on.’ And there was this focus group, and then media people came in: ‘Where will Al be sitting? Will Al have the punchline?,” Leno said.
