A show with an 11 year old boy with a "flaming hair", with a red-haired 15 year old twin genius sisters with a streak and attitude of an hoe, and their main purpose on the show is to drool over a weird fucking guido. Those twins deserves to be discriminated by calling them gingers. Johnny test, the protagonist is the one who tries hard to be cool but he instead looks like a rampant cockmunch that has an iq of an 9 year old, poses that he likes heavy metal or rock, but all he listens to is music full of power chords. You'll waste your time if you watch this, thus, decreases your iq to hell. It's basically a rip-off of the famous "Dexter's Laboratory".
Fanfag: JOHNNY TEST RULEZZ!

Smart person: It sucks, go watch some more to melt your brain.

Fanfag: WHAT?

Fanfag 2: Johnny test is soo cool, he listens to rock.

Metalhead: Fuck you both, he's just listening to a boombox full of power chords in it! He doesn't know real metal or rock! *gives megadeth, iron maiden, anthrax CDs*
