Verbs is Funny
A boy who swims may say he swum,
But milk is skimmed and seldom skum,
And nails you trim; they are not trum.

When words you speak, these words are spoken,
But a nose is tweaked and can't be twoken.
And what you seek is seldom soken.

If we forget, then we've forgotten,
But things we wet are never wotten,
And houses let cannot be lotten.

The things one sells are always sold,
But fog dispelled are not dispold,
And what you smell is never smold.

When young, a top you oft saw spun,
But did you see a grin ever grun,
Or a potato neatly skun?
