My sixth grade teacher, I assume to make a weird point about how English is basically a massive loose pile of exceptions, had the whole class come up with a torturedly extended version of the "I before E except after C" rhyme. This was almost 30 years ago but I still remember some of it:
I before E, except after C
Unless it sounds like an A
As in "neighbor" and "weigh"
"ch" and "sh" don't count as a C
etc.
