Nobody should be completely without wits, even if they are made entirely out of straw.
Never fear for the Scarecrow, though, as by the end of the tale of the 1939 film The Wizard of Oz, it turns out that he's been the most intelligent of the travelers all along! Sounds like he just has some low self-esteem issues.
But you can change all that! Make the Scarecrow feel like he's wanted and worth something by buying this Wizard of Oz Scarecrow Corn Statue, which features an incredibly-detailed 6 3/4-inch tall resin statue designed to look just like Ray Bolger's character from the movie!
The Scarecrow is portrayed in this statue resting upon a fence pole near some stalks of corn.
