"Here's his beach hat..."
...which I am determinedly not picking up!
I like this sketch a lot, but I think it would have been even funnier if Sherlock Hemlock had shown up wearing beach clothes.
Sherlock Hemlock is not always this helpful. Usually his declaration of himself as the "world's greatest detective" is meant to be taken ironically. Good thing for Bert he wasn't being ironic in this sketch, though! And good thing puppets don't need to breathe!
