They used to call him Speedo, but his real name is Mr. Earl

 

"I have always loved the Roadrunner/Wile E. Coyote cartoons, some of the best animated shorts ever made. 

Chuck Jones was an absolute genius. 

Imagine my dismay when I discovered the Roadrunner (Geococcyx variegata) has a top speed of approximately 20mph/32kph, and the Coyote (Canis latrans) can attain 35mph/43kph. 

My childhood was a lie! "

Google underwrites him:

"While Looney Tunes' cartoon roadrunner might have been able to out-run the coyote every time, real-life roadrunners aren't so lucky. Coyotes out-pace the birds substantially, clocking up to ~43 miles per hour, compared to a roadrunners ~20 miles per hour. "
