If you give a bear a home for the weekend, he'll want a ride back to school on Monday.
Meet Bernard. He lives in Mrs. R's classroom.
Last weekend, my nephew was the lucky student who got Bernard. His mom was not so lucky. She had to carry Bernard home. It was a heavy load to bear. So I offered to give Bernard a ride back on Monday. I could bearly get the seat belt around him.
It was a grizzly experience.
(Help me out here -- can you think of any other unbearable puns?)
