:-) I imagine this sung to the tune of "Log" by Ren & Stimpy:
"What rolls down stairs alone or in pairs
Rolls over your neighbor's pug?
What's great for a drink and fits in your sink?
It's Mug, Mug, Mug!
It's Mug, Mug, it's small, it's heavy, it's clay.
It's Mug, Mug, it's better than bad, it's meh...
Everyone wants a Mug! You're gonna love it, Mug!
Come on and get your Mug! Everyone needs a Mug!"
