Donald Duck #37/2001

In "null," Donald Duck’s theatrical ambitions spiral into delirium when he becomes so immersed in rehearsing for "Man of La Mancha" that he convinces himself he’s Don Quiduck. With the only key to Uncle Scrooge’s new vault door tied to his lance, he rides off in a delusional quest, prompting a frantic chase by Scrooge, Kwik, Kwek, Kwak, and Katrien. Meanwhile, the Zware Jongens watch closely, ready to exploit the chaos — and the priceless slip of paper — for their own gain.
