Happy Howell-o-ween

I was working in the lab, late last night,
When my eyes beheld, an eerie sight.
For this monster from its blawg began to rise,
And suddenly, to my surprise,

She did a Howell-o-ween mash-up Blawg Review.

Now everything's cool, Howell's a part of the band
And her monster mash is the hit of the land,
For you the living, this mash was meant too
When you get to my door tell them Denise sent you.
