That's my new superhero alter-ego. Super-Chipper Girl blinds the bad guys with her dazzling smile, and giggles them into submission. Her weaknesses are rainy days and reality checks. However, her super-chipper energy shield is self-healing, so chinks don't stay long.
This whole thing started as my self-deprecating joke on Twitter and somehow...evolved. Darcknyt got an idea for a Super-Chipper Girl header, Falcon joined in, and the final result is what you see above. Then I bragged about my new header to Ian, who became inspired and promptly whipped me up a lady to go with the theme.
Pretty cool, huh? I'm keeping the new header for a while. It's fun.
