My 5 year old's sense of humor is killing me

So my kid says to me this morning, 'Dad, why did the cookie go to the doctor?' I say I don't know. He goes, 'Because it felt crumbly!' Then he just loses it laughing like he just told the funniest thing ever. I laughed for like 5 minutes straight. Pretty sure that joke doesn't even make real sense but man, the confidence and delivery. That's peak comedy right there.
