Hairy Maclary

...from Donaldson's Dairy

Schnitzel von Krumm
with a very low tum,
Bitzer Maloney
all skinny and bony,
Muffin McLay
like a bundle of hay,
Bottomley Potts
covered in spots,
Hercules Morse
as big as a horse....

AND Hairy Maclary from Donaldson's Dairy.

Yes, you're right, I do know it off by heart.
