Limericks: Round Two

There once was a man named Morris,
Who tried it on with his local flourist,
He handed her flowers,
But she said 'aren't those ours?!'
That cheeky young man named Morris.

I went in a spaceship to Mars,
Where I met lots of cats driving cars,
I said 'what's this about?'
In reply they did shout,
'There's no driving restrictions on Mars'

I wanted to write a good poem,
To my Granpy who lives in Dun-Boeing,
ahhh... writer's block...

It's a knockout.
