10 TV Show Mistakes Directors Left In Because The Acting Was Too Good

10. A Blue Blazer Blunder Leads To Gold (Friends)

If you ever needed a reminder of just how unrivalled the electric chemistry possessed by the titular group of Friends truly was during the NBC smash hit's days as the biggest sitcom in town, then look no further than the way they handled Matthew Perry's hilarious verbal misfire during Season Four's The One with Phoebe's Uterus.

With the Chandler Bing star tasked with delivering the line "Donald Trump wants his blue blazer back," Perry unfortunately found himself fumbling out the world "black" at the end of that attempted zinger.

Far from allowing this clear error to derail the bit though, Perry was soon met by wave after wave of brilliant improvised digs from the likes of David Schwimmer and Jennifer Aniston, as the friends rolled with the mistake. And the creative squad behind the episode found the entire exchange so unexpectedly hilarious that they felt it was more than worthy of making the final cut.

When you throw this many brilliant comedy minds into a room, a few unanticipated moments of side-splitting improv are to be expected. And this particular set of unplanned utterances helped save the slightly botched scene, all while hilariously poking fun at Perry in the process.
