Am I really having this conversation?

In my bathroom, trying to gain a few seconds of peace before we head out the door,Lily comes in.
Lily, "What color would my throw up be if I ate a cucumber?"
Me, "Green, I guess"
Lily, "When I ate Cheetos, my throw up was orange"
Me, "Yep"
Lily, "What color would it be if I ate a green pepper?"
Me, "Green but you won't eat a green pepper"
Lily, "And if I ate squash, it would be yellow"
Me, "Yep"
Lily, " And if ate meatballs, it would be brown"
Me, "Can we talk about this later?"
