It's the Easter season again!!!!

So I figured I'd post the lyrics for my errr umm... favorite easter chant. 10pts for anyone that figures out where it came from ;)

Sanctum Piter oteum, Deus ore uneum.
Hippitus hoppitus reus homine.
In suspiratoreum, lepus in re sanctum.
Hippitus hoppitus Deus Domine.
