(read it on mathstory.com)

lyrics:

1 and 1,
Smelly Shoes,
Make 2 very,
Stinky shoes,
1 and 1 stinky shoes,
Give you 2 stinky shoes,
1 and 1 add up to 2,
Very, smelly,
Stinky shoes,
I don’t know what I will do,
With these very stinky shoes,
Stinky, stanky,
Smelly, danky,
Scented, dented,
Stinky shoes...
What will I do with these shoes?
Stinky shoes,
Stanky shoes,
Pee-yoo, Pee yoo pee you shoes,
Pee-yoo shoes, Pee you shoes,
1 + 1,
Give you 2!
Pee-yoo, Pee yoo, pee you shoes,
Pee-yoo, Pee yoo, pee you shoes,
1 + 1,
Give you 2!
That’s a pair to me and you!!
Stinky, stanky,
Smelly, danky,
Scented, dented,
Stinky shoes...
What will I do with those stinky shoes?
Stinky Stanky,
Pee yoo, danky,
Icki, yicki,
Mucky, yucky
Scented, dented
Muddy, ugly
Dirty, dingy
Filthy, grimy
Grubby, reeky,
Filled with fungus,
Rotting shoes,
Are among us,
Icki yicki,
Mucky, yucky.
Muddy, ugly,
Dirty, dingy,
Stinky, stanky,
Smelly, danky,
Scented, Dented,
Stinky shoes...
1 and 1,
Give you 2!
Smelly, smelly, smelly,
Smelly shoes!!
1 and 1,
Give you 2!
Smelly, smelly, smelly,
Smelly shoes,
Pee you shoes,
Pee your shoes,
Pee you!! Less
