Friends: The Worst Thing Each Friend Has Done!

Ross is the loveable goofball that really acted as the glue for the series. He was affable, kind, good-natured and only occasionally prone to fits of jealousy and anger. Wait, what was that last one? Yes, while Ross was a sweetie for most of the show, he really did score the gold medal for being the most sinful member of the group, as he did some pretty deplorable things.

This iconic palaeontologist has cheated (unless you do think they were on a break), had violent outbursts (lest you forget the sandwich incident), and even seemed to abandon his son (poor little Ben). Still, nothing is worse than this reprehensible act that made him seem pathetic, creepy and totally irrational.

After Ross and Rachel drunkenly got married in Vegas, she asked him to fix their annulment. But, in fear of having another failed marriage, he lied to her and claimed he had taken care of it, only to reveal to Phoebe that they were still married. He then planned to keep this a secret from Rachel until the truth came out.

Now, saying the wrong name at the altar was bad, but it was a Freudian slip, thus, accidental. This, however, was entirely planned. It was selfish, possessive, morally corrupt and overall, made Ross seem like an awful dude. Not a good look Ross, not a good look at all.
