Tell us about it, Janet! 

Originally from Rocky Horror Picture Show, the phrase is now used when someone is about to tell you a story you don't want to hear, in the hopes that they will be confused/distracted enough for you to change the subject or flee the scene.

Exercise caution when the mark is actually named Janet.

Talia: That reminds me of when I had a four hour conversation with Ben Stein about economic theory...
Bruce: Tell us about it, Janet!
Talia: Wh-
Bruce: *flees*

"My car broke down on the highway in the pouring rain, and I had to wait for hours for a tow truck." "Tell me about it," my friend replied, sighing as they clutched their own dead phone. (Their sigh and clutching the phone imply they're also stuck in a difficult situation).
