What's the capitol of South Dakota

Made a cuppa coffee this morning Forgot about it I think I ate breakfast Can’t remember what I combed my hair Singular Musta brushed my teeth They’re back in my mouth I wear a shirt that reads “IF FOUND PLEASE RETURN” Socks that disagree with each other Shirts that read like a virtual menu Shoes that tie themselves The best place to look for my glasses Is in the lost and found pile I shave when my beard Gets to that itchy stage Bathe when the dog moves To the far end of the couch I laugh a lot Not always sure why Or for what reason I have children And phones That are smarter than I am Yet nowhere near as wise When my doctors ask “any questions” I reply “yeah, what’s the capital of South Dakota” They are generally not amused I don’t think they know….
