Tom, did you see that Cornelius skipping down that hill in his highwater cargo pants with a skidmark on the back eating a ring pop?

Look at the Cornelius over there with Oreo cookie crumbs around his mouth smiling at Prudence across the room?

Wow, you can see a perfect outline of that Cornelius' butt through his overalls ski pants.

A Cornelius is the smartest most loving and kind man you’ll ever meet. Aside from his unique name comes in interesting personality although he’s stubborn he’s a soft person at heart to people he loves most and is very good looking it’s easy to get trapped in their beautiful green eyes. When you meet a Cornelius keep them they’re really important people and never disappoint especially when you’re dating a Cornelius. They show you off to all their friends and kiss you in public and make sweet gestures. A Cornelius loves to give and receive subtle gestures.
