What Did We Learn?

From OAPedia.com

What Did We Learn?, AKA What Did You Learn?, is a segment that is done (though not all of the time) at the end of the show which involves listers calling and sending Instant feedback, telling Opie and Anthony something that they learned from listening to that day's show. This often involves funny callbacks and/or funny quotes from a member or guest of the show.

This used to happen at the end of practically every show, but due to the fact that the current XM show has no definite end time, the bit has died out. O&A have periodically tried to revive it (for example, doing it at the end of the terrestrial portion of the show, which generally ends around the same time each day). Currently, O&A are doing What Did We Learn? in place of The Line of the Day.
