While browsing my flist, someone somewhere posted a link to the Sherlock Holmes IMDB board where they're coming up with titles to NOT name the sequel.
See it here. Here are some of my favorites:
Holmes Alone: Watson Moved out (A.K.A) Me, Myself and the Dog
Sherlock Holmes: The Count of Watson's Fisto
Sherlock Holmes: Crouching Holmes, Hidden Watson
Sherlock, She Wrote
Sherlock Holmes and Gardens
Sherlock Holmes 2: Sherlock, Stock, and Two Smoking Barrels
Sherlock Holmes: The Spy Who Shagged Me
Sherlock Holmes 2: Deduce this
Sherlock Holmes: Kiss Kiss, Bang Bang (wink wink)
Sherlock Holmes: Honey, I blew up the dog!
Sherlock Holmes 2: It's Elementary, Bitches
Sherlock Holmes: 1.21 GigaWatson
...I about died on the last one. Gnite!
