Escaping " and ' in sed

Okay, I have looked through everything and cant find it...

I need to append a line to the end of a a file: I can do it like this:

sed '$ a\additional line' -i file.txt

However, the extra line I need has both " and ' in it:

ie, "additional" line's has to be added.

sed '$ a\"additional" line' -i file.txt

works fine, but

sed '$ a\"additional" line's' -i file.txt

doesn't. I have tried a huge number of escapes, ie \', or using "" as the outside quotations, but I can't get anything to work.

Any help???

Thanks guys
