What can I listen to with little kids in the room?

I have a 2-year-old and a 5-year-old, and they’re starting to pay more attention to (and repeating) what they hear on my podcasts. I tend to listen to comedians messing around (Threedom, Doug Loves Movies, Staying Alive), so they get inappropriate quickly.

Any suggestions for kid-safe podcasts?

Just to be clear, I’m looking for G-rated podcasts for adults, NOT content specifically for kids. So far, I’ve got Wait Wait Don’t Tell Me and Good Hang with Amy Poehler.

Also, using headphones does not work well for me.
