Thomas walks to grandma's. He thinks of a poem for her. But on the way, everything goes wrong.

What rhymes with... Do you rhyme along?
Hey, what's lying there on the sidewalk...? A lady's bag full of candy.
Oops, a dog disappears behind a shack with it. There's a loud... scream.
Two posh ladies start screaming loudly, they have thick... strict black glasses.

When Thomas finally arrives at grandma's, it's a big party.
'Bye grandma. I tried to get there on time, but there was something on the sidewalk...'
'POOP!' shouts grandma.
