Let's talk about anal worms.
If you'd rather not, feel free to move on to something else. You won't hurt our feelings.
On a new episode of "The Joel McHale Show" on Netflix, actress Kristen Bell shared — more like over-shared — that she and her young daughter got anal worms, aka pinworms.
McHale thought Bell was joking when she blurted out this little nugget of yuck.
Never miss a local story.
"Was it painful?" he asked.
"No, but it was very itchy," Bell said to a wave of laughter from people in the studio.
The perky woman who famously gave voice to Princess Anna in "Frozen" was downright enthusiastic in discussing her anal issues.
"I’m not here to talk about pinworms, but I will,” she said before launching into a discourse.
"Fifty percent of people over 15 don’t experience symptoms, which is the itch. And your kids get them because they put their hands in their mouth and they lay eggs.”
Bell and her husband, actor Dax Shepard, have two daughters — Lincoln, 4, and Delta, 3.
She said she noticed that the carpeting had been removed at her daughters' preschool. When she asked about it, she was told it had been removed because of a case of pinworms at the school.
She immediately consulted Google, where she learned the worms are "so, so contagious."
As luck would have it, she then noticed "of course, my 3-year-old was (scratching) for like a week. And then you have to monitor it and you have to look in their poop and when you wipe their butt. Sure enough, I wiped ... saw a little white worm."
The people in the studio went "ewwwwwww."
“I know, she’s really gross — my daughter, not the worm," Bell joked. "The worm was gross too."
Later that day, Bell noticed she was itchy, too.
Pinworm infection is the most common intestinal worm infection in the United States, occurring most often in school-age children, according to the Mayo Clinic.
They worms are thin and white, about one-fourth to one-half of an inch long. As the infected person sleeps, female pinworms lay thousands of eggs in the folds of skin around the anus. The microscopic eggs easily spread from child to child.
Like Bell said, most infected people don't have symptoms, but when they do it's typically itching and restless sleep, the clinic says.
Treatment involves oral drugs that kill the pinworms and thorough washing of bedding and underwear. The entire family needs to be treated for best results, the Mayo Clinic advises.
The entire Shepard-Bell household had to drink a "shot of chalky nonsense" treatment from the drug store, the actress said.
"But I don’t think anybody got it but me and Delta, she said.
Before she walked off-camera, Bell grabbed McHale's hand and shook it hard.
"Good to be here, Joel!" she joked as he looked at his hand in mock disgust.
