This is a song by Ween, from the album
God Ween Satan: The Oneness.
This gem from Ween's first studio album is interspersed with garbled high-pitched vocal weirdness in between multiple repetitions of this chorus:
i got a weasel
it's a teazel
mah pleazel
mah pleazel
got a weasel.
The other voice screams things like "Oh this big weasel!" and "Big weasel jump in the air!" At one point that functions as the "bridge," the main vocal just begins yelling "weasel, pleazel pleazel pleazel got a weasel it's a teazel mah pleazel!" It sounds almost Fat Albert-like.
The music is again jaunty and very goofy, and you can almost see a weasel jumping around terrorizing people.
