The recovery move used by Fox in all 3 installments of the the Super Smash Brothers series, it does a decent amount of damage but it often countered due to its large cast time.

Best browser out there. Oh, it only uses more resources than IE because IE is integrated in windows, therefore, IE uses all the resources that windows ues :p, it is slower for the same reason, it isn't integrated, but, it isn't a security hole, plus, it isn't made by microsoft, double plus, and it is much cooler, too cool to use with windows, switch to LINUX you fools! And drop the mac off in a dumpster on the way. Peace!

The uber-pwner of IE. Has less security issues, a pop up blocker, a blocker for those "Guess whose celebrity's legs these are to win a free PSP!" ads, and tabs, bitch. Also uses its brain washing tricks to force all other browser users to convert to Firefox, like Muslim terrorists.
Internet Explorer User: Hmm...I wonder what Firefox is.
