I just had this (other) sick idea...

How about an American Idol parody with Team Fortress 2... Your favorite Classes singing popular songs? I was just driving to get some material from somewhere, and on the whole trip i was thinking about it...

The engineer singing Lemon Tree... Showing him, bored in the intel room. Waiting for the scout to rush in front of his sentry... and at the last verse "im stepping around in the desert of joy" the leaves and builds a sentry on the rooftop of the bridge...

and shortly before arriving i came up with Medic and heavy singing "Opposites attract" by paula abdul (medic = paula)

anyone got a funny idea too?

A few pyro's singing billy joel's  "we didn't start the fire", and then show like 10 enemy soldiers on fire at the end.

Demoman singing kiss me im shitfaced by the dropkick murphys
scout singing cant touch this by mc hammer

A chorus of pyros chanting "The roof is on fire", by the bloodhound gang in muffled mphs...

A heavy weapons guy singing barbie girl, imagining his gun as ken...

A soldier doing the YMCA (don't ask don't tell!).

A medic singing "I'm a little teapot" for obvious reasons, handle + spout = his healing weapon, steamed up + shout = charging his ubercharge and using it. Can't remember the name of his healing hose thing.

Spy singing Secret Agent Man.
