Oral exam

I'm going to have an oral exam.
We've to act a drama for it..
I thought I drama about making mistake in telephone..
Like,,
Student A called Student B..
But Student B was not at home or having shower..
And Student B's sister got the phone,
Then Student A asked Student B's sister to tell Student B to bring sth for BBQ...
But Student B's sister made mistakes, she told her brother to bring the other things..
--
So I need some rhyme words that the sister can hear wrongly..
At least 5 pairs..
