Insurance salesmen are premium lovers. Interior decorators do it all over the house. Inventors find a way. Janitors clean up afterwards. Jewelers mount real gems.
Jockeys do it with whips and saddles.
Joggers do it on the run. Jugglers do it until they drop. Jugglers do it with more balls. Julia Child does it with asparagus and Hollandaise sauce. Landscapers plant it deeper.
