When you have Lindsay Lohan on your show, it’s probably difficult to really plan around what exactly will go down. David Letterman had her on last night, and when he asked about his former foe turned pal, Oprah, she suggested they give her a bell.

Dave is clearly uncomfortable with calling at first, but then just goes with it and it turns into a pretty funny bit.

Oprah has been helping Lohan, and they appear together in the reality TV series, 'Lindsay' on Oprah’s OWN network.

It’s stuff like this that makes us wish Dave wouldn’t actually retire. Legend!
