If I Could Choose My Imaginary Friend

It might be a T-Rex dinosaur to scare off big bullies with a roar or Archimedes to help with math; while I linger, ponder, in the bath. A space astronaut would be quite swell to give me some super tales to tell. A friend like a Prince, King, or Queen may keep the bitter, spiteful boys away. Perhaps that tin man who found his heart because I do not know where to start; just anyone who can show me how Shelly, Byron, Leopardi, ciao! Each night I lie, imagine my list doctor, nurse, Olympic medalist, the man who discovered old King Tut, a dashing knight, a train driver; but, I am blessed with Eugene - in pink hat, who does not do anything like that.
