I'm not sure how much of this is parody or not, but the best part is the end when the kids get bored and try to leave the set. Then there's some great laser deaths.

Suddenly my day is a little bit better.

Oh man, I've got a new favorite song. One parody giveaway: "I've got this pi shit backwards and forwards." would never be said on a real kids show.

But they've totally nailed the genre of Public Broadcasting 80s Children's Programming. Well done.

Yeah, that and the creepy guy in the wrestler's mask.

Plus I can't tell exactly, but the non-pi lyrics sound kind of dark. Something about wrathful gods maybe.

I did a little digging, and found the song is by a group unsubtley called Hard 'n Phirm. You can find an album on itunes with the pi song.

lyrics

When ink and pen in hands of men
Inscribe your form, bipedal P
They draw an altar on which
God has slaughtered all stability
No eyes could ever soak in all the places you anoint
And yet to see you all at once we only need the ·
Flirting with infinity, your geometric progeny
That fit inside you oh so tight
With triangles that feel so right

Your ever-constant homily says flaw is discipline
The patron saint of imperfection frees us from our sin
And if our transcendental lift shall find a final floor
Then Man will know the death of God where wonder was before

Yeah, I know this Pi shit backwards and forwards
Check it out

I did three chicks then I pointed at the door
A girl entered in so that made it four
I snapped one time in came another five
Add 'em all up and that makes nine
The average age 26.5
Now that's what I call gettin' some pi
Five of the chicks wore 6-inch heels
Two of the nine squealed like seals
514 was the area code
Quebec, Canada my winter abode
And my 1.3 million dollar chalet
Pi backwards, pi forwards, all night and all day
