Jay Leno tagged in on The Tonight Show last night to “help out” NBC, which has found itself one of the more interesting storylines of this head-smacking White House race. While Tonight’s current host Jimmy Fallon was dinged in some corners for a recent hair-mussing appearance by GOP hopeful Donald Trump, the show’s former host reveled in a string of old-school Trump barbs.

Leno also expounded happily on NBC’s uncomfortable and ongoing Billy Bush/Access Hollywood chapter. Trump recently insinuated he’s mulling a lawsuit against NBCUni over the leaked 2005 tape of a Trump/Bush Access Hollywood hot-mic conversation, in which Trump boasted about having a famous-person’s Grope Women With Impunity pass. NBC recently let go Bush over his remarks and actions in the recording, while issuing a statement wishing him all the best, thanking him for his service, etc.

Leno, last night, said this:

“I had a great costume this year,” Leno said during his Halloween guest-monologue. “I put a douchebag on my head and went out as Billy Bush.”

Leno also let fly a string of How Bad Is The Economy gags, and took a couple pokes at Hillary Clinton: “Hillary Clinton got quite a scare tonight. I guess a trick-or-treater came to the door dressed as a lie detector.”
