Can't say no long words

In that case, says Fido

You CAN say some long words

If you profess 'I CAN'T say NO long words'

Oh, you know all the grammatical stuff, Fido

The double negatives, and all that rubbish. lol.

But I can't say ANY long words

They all seem to end in 'wotsit'

Or 'thingy', or 'watcha-ma-call-it'

I mean, those iambic penta-thingys (pentameters)

And meta-wotsically speaking in some poems (metaphorical)

And I hardly get the meaning of any cryptic-watcha-ma-call-it (crypticness)

And who's Joe Bloggs (a UK expression only for 'any man'?)

And have they caught Bill Stickers yet?

Or his mate Bill Posters?

They're gonna be prosecuted

Why, what they done?!

This must cease, says Fido

These prehistoric, corny jokes

It's only you that still laughs at them these days

He says to me

As you've told us them 5 million times!

And this must stop too - 

Using a thousand words when 5 will do!

Heehee.
