Cake is very useful
It has a lovely taste
It's comforting and yummy
But it ends up round your waist.
A wheelchair's very useful
It helps me get about
But last time someone pushed me
They nearly tipped me out.
Weather's very useful
when you've nothing else to say
You can talk about the weather
And what it's like today
BCG is useful
It helps to pass the time
Instead of writing good stuff
You can waste it here in rhyme
