Watching Jane Fonda and Lily Tomlin in interviews for their Grace and Frankie promo is always a delight, as the pair often fall into Odd Couple character to hilarious results.

Their appearance on the Late Late Show with James Corden was no different.

The pair talked about sharing a trailer on the set of the show, which is set to end on Friday.

The trailer had a thin wall between so I could hear everything, says Fonda.

She destroyed my life because I am sitting there seriously while my very creative team makes me look human and she takes a lot longer than I do. I mean, from the gut. What does she do that makes people laugh? I apologize to my guys for everybody laughing on her side of the wall.

They were having a good time. It all has to do with the wig.

Lindbergh was hidden in that wig.

The final season of Grace and Frankie will be available on the internet on Friday.
