When I lived in Provo, I had a catalpa tree that did this very thing. One minute it would be covered with leaves, and the next minute the branches were bare and the lawn was ankle deep in catalpa leaves.
This gag also reminds me of my missionary trainer. He tried to teach me all kinds of things...but not a lot of them had to do with being a missionary. Bless his heart! I learned a lot from him!
I've been cartooning since I was a teenager, and have been published in magazines ranging from AASHTO Quarterly to the LDS Church magazines and several other periodicals, trade publications and newsletters.
