Lisa Kudrow explains her random 'Friends' wrap party gift from Matthew Perry

It's always good to double-check your background before starting a video call, especially if that call is going to be broadcast on live TV.

In her video chat with Jimmy Kimmel on Tuesday, Lisa Kudrow's background game was A+ — not only did she frame herself in front of some lovely wooden shelves, but she also had some handy Friends memorabilia in the background for a spot of show and tell. That "Cookie Time" jar over her shoulder? Actually a prop from Monica and Rachel's apartment, which Matthew Perry gave her when the show wrapped as part of a long running in-joke.

Apparently it stemmed from a much earlier scene in Friends, where Kudrow had to say the line, "Ooh, I better get going!"

"Except I didn't have a watch," explains Kudrow. "It was too late when I realised I don't have a watch, how do I know 'Ooh, I have to get going.'? And so, as the words were coming out, I gestured to that and said 'Ooh, look at the time, I better get going!"

Perry's response?

"Did you point to the cookie jar and say 'Look at the time?'"

Makes sense.
