knock knock

James wanted to do knock knock jokes today during our lunch at Tiny's.  "Do it like natural disasters!"  I obliged (rather pleased with myself)  "Knock, knock"  "Who's there?"  "Sue"  "Who Sue?"  "Sue-nami!"  James seemed more pleased with his version "Knock, knock" "Whos' there?" "Tri-State Tornado!" "Tri-State Tornado who?"  "No, Mom, it's just Tri-State Tornado!"
