The mother/daughter chemistry that Jamie Lee Curtis and Lindsay Lohan had in "Freaky Friday" will always be memorable. Even though it’s been almost 20 years since "Freaky Friday" came out, this duo recently touched base with each other. In fact, Lohan and Curtis use a secret code to make sure they are texting with the right person when they do catch up.

It’s hard to believe it’s been almost two decades since we saw Jamie Lee Curtis and Lindsay Lohan switch bodies after opening up mysterious fortune cookies.
