Oh, let's see...

Nerima Home Companion, brought to you by Kona-Nyuu Okonomiyaki, in the brown
bag with the dark stains that indicate freshness.  Heavens, they're tasty
and expeditious.  Kona-Nyuu Okonomiyaki, that give shy people the strength
to get up and do what needs to be done.

(I couldn't come up with a name, so I resorted to the dictionary.
Kona=powder and nyuu=milk.)

Or...

This portion of our show is brought to you by Makimura Mallets.  Ladies, are
perverts your problem?  Try Makimura Mallets, in sizes ranging from 10 tons
all the way to 2 million horsepower.  Makimura Mallets, when you absolutely
need a bigger hammer.

It's been WAY too long since I've listened to PHC, and I'm not *that* good
at humor, so anybody please feel free to elaborate.  It just wouldn't be
Nerima Home Companion without commercials!


Dunno... wanna take a crack at one?  Nuku-Nuku's Kitty Boutique
(yeah, she's s'posed to live in Nerima, too, y'know) comes to mind,
but anything's possible...
