Apparently, it's her favorite "dirty joke," and she used it to kill the awkwardness of a power outage at her Brisbane, Australia show.
"Shall I tell you my filthy joke despite all the children here?" she asked her audience. "I need more applause than that because I might offend someone."
”What do you call a blonde standing on her head? A brunette with bad breath.”
I know; gross. But show me a kid that gets that joke and I'll show you a kid way too exposed to that kind of humor already, so don't blame Uncle Ron!
Actually, it's not the first time she's dropped that whopper on her audience. Roll this from March 7th.
She explained the power outage, too, then went on.
