I was always useless at memorising poetry and stuff. I tried putting the poems into my own words as a reminder. The problem is that I only remember my versions now and have forgotten the originals!
Here's my memory aid for a well-known bit of verse but sadly I can't remember the original version. Can you sort it out? There's bits of British slang in there so I hope you'll understand it.
Pwhoar what a scorcher! Yes you!
Not bad looking and you keep yer lid on too
Flatulence shocks my sister's dearest friends - phew!
Question
What is my sister's name?
Note: I have this tagged as word. The single-word answer will be the given name of my sister. For example, Elizabeth. I am not certain whether this should be described as a riddle.
