Have you ever stopped to think about what rats do for fun?
Sure they crawl around and scurry,yeah they're always on the run but a rat sure likes a good timejust like you and me
I'll prove it with a tale about a rat-infested brewery
It started with a little lad named vermin 
McCannwho fell upon a drink that made him feel like quite a manhe rounded up his furry boys,though some wore a frownthey quickly changed their tune and they slammed a couple down.[Chorus:]
One, two, one-two-three-four!
Come on all you good ratswe'll send you to heaven you'll find the pearly gates in the froth and the foam'cause in these vats you've made quite a creationa potion that turned the 
Guinness to gold!
Like mice behind a piper,rats from all around soon headed for this factory in old 
Dublin Town.
They surely heard the news about this fancy new rat-brew they come,they saw, they had a taste and knocked back a few
The rats were in a tizzyaddicted to the bone the hairy lugs were giddythey were never going homelike a bunch of drunken pirates prepared to walk the plank they drank,they sang, they took a plunge and in the beer they sank!
