Mom, I need to clean my thumbs

In the car on the way home from the grocery store ...

Toddler: "Mom, I need to clean my thumbs" as she holds them both up in that "thumbs up" sign.

Me: "Umm, okay. We can clean them as soon as we get home."

A few minutes later, as I am unbuckling her from the car seat, I look closer at her thumbs.

Me: "Are those buggers?"

Toddler: in her sassy, 'duh' voice, "Yeaaah"

Me: "Did you pick your nose with your thumbs?"

Toddler: "Mmm-hmm"

Me: "With your thumbs? Weird"

Toddler: "Well mom, we were in the car."

Me: "You have to pick your nose with your thumbs in the car?"

Toddler: "Duh"

And thus, the life of a mom.
