When Ed Lover and Monie Love were talking about the new planets NASA announced they found this week, the conversation somehow shifted to the slavery era in the United States. Big City accidentally revealed that he has actually had no idea what the Underground Railroad really was his whole life, as he thought it was a series of tunnels.

While this is a little better than Atlanta Housewife Porsha Williams‘ 2013 on-air Underground Railroad flub (she thought there were actual trains involved), it’s still pretty bad. Monie Love & Ed Lover brought him up to speed on what the Underground Railroad really was, in this exclusive clip from the “Ed Lover Show.”
