The Rhyme

But here by popular demand is the rhyme:

One potato, two potato, three potato, four,
five potato, six potato, seven potato more.
Icha bacha, soda cracker,
Icha bacha boo.
Icha bacha, soda cracker, out goes Y-O-U! 

And here is another version from a Welshman and fellow roboticist:

One potato, two potato, three potato, four,
Five potato, six potato, seven potato, more.
Ible-oble black bobble,
ible-oble shout.
Shining on the mantle piece - YOU ARE OUT!
