By now, you've read about the new city in Animal Crossing: City Folk. The itinerant characters like Gracie and Lyle now have their own shops in the new "City" area. Two new locations in the city, as I found in my hands-on session, combine to form a shortcut to hilarity.
A theater in town offers stand-up performances from Wild World's Dr. Shrunk, which (through his reactions more than his actual terrible jokes) teach your new avatar an emotion. You can then trigger these emotional responses with an icon on the onscreen keyboard or an icon located at the top of the gameplay screen. I got "sorrow," which causes the character to cry briefly. Heartbreaking!
The Nintendo rep then led me into the new beauty shop, where you can give yourself a makeover in the form of a Mii mask. I chose the Iwata mask for my avatar Sarah, which replaced her Crossing-style head with Iwata's. This odd sequence of events left me in a position to make a cartoon version of Nintendo's president, clad in a dress, weep. You can see a picture of said crying jag after the break.
