Want to hear a chimney joke? Got stacks of them! First one's on the house.

Tell It Well

Build to Both Punchlines

Chimneys are commonly called stacks, so “stacks of them” turns a large joke supply into part of the house. “On the house” then means both free of charge and physically above the roof. Ask the opening as though offering one quick joke. Let the first answer get its own beat before adding the second as a bonus. The extra turn works best when “on the house” sounds like an ordinary generous offer rather than a phrase chosen for the roof image.
