it's not quite pong, but...

i have a total soft spot for those old-school web-based flash games, the ones that made the internet fun right after al gore invented it so long ago. one of my favorites, then and again now (with a souped-up but still really basic version) is garfield's lasagna from heaven game. i just remembered that garfield was one of my bookmarks some ten years ago (along with sanrio and a few others) and that i loved this game then. turns out, it's still crazy fun.

other super awesome ones:

little red square game (caution: really addictive)

copter (caution: outrageously addictive)

midget tossing (caution: not exactly politically correct)
