My mom asked my doctor, "Why is my unvaccinated baby crying?"
The doctor replied, "He's going through a midlife crisis."
Listen up, buttercup. The joke is funny because babies don't have midlife crises. People only have midlife crises when they start to get old and realize they have wasted their entire life following you on social media. The baby is unvaccinated, so he may not even get to have a midlife crisis.
