Pointing to a recent poll showing that Americans now give Mr. Bush a 61 percent favorability rating, Mr. Ferrell said: “That’s right. Donny Q. Trump came in, and suddenly I’m looking pretty sweet by comparison. At this rate, I might even end up on Mount Rushmore, right next to Washington, Lincoln and I want to say, uh, Kensington?”

But before anyone started wishing for Mr. Bush to return to office, Mr. Ferrell said, “I just wanted to address my fellow Americans tonight and remind you guys that I was really bad — like, historically not good.”

He added: “Don’t forget, we’re still in two different wars that I started. What has two thumbs and created ISIS? This guy.”

Reviewing a chart that showed the decline of the stock market during Mr. Bush’s presidency, Mr. Ferrell said, “I’m no economer, but even I know, that was no bueno.” Going on to compare vice presidents, he added: “Some say Mike Pence is heartless. But remember, Dick Cheney was literally heartless. At this point, it’s just Legos in there.”

And if Mr. Trump thinks the news media is tough on him, Mr. Ferrell reminded viewers that an Iraqi reporter had once thrown a pair of shoes at Mr. Bush.
