Simple and humorous, I love these hat lamps inspired by pop culture personalities. I found the fixture below on Design Milk, it's called Chaplin and it was designed by Martin Hirth. The metal lamp shade can be adjusted and set at different angles by balancing it on the wood base and it can be used as a table lamp.
The Billie and Lean are a table and lamp combination by MONOCOMPLEX. The side table Billie and floor lamp Lean are inspired by Michael Jackson's infamous dance moves you've seen in videos for "Billie Jean" and "Smooth Criminal".
Jack Phipps designed these playful pendants made with authentic bowler and top hats. The collection represents Jeeves and Wooster, characters from a classic British comedy.
