Friends: The Worst Thing Each Friend Has Done!
3. Joey - Took A Stuffed Toy From A Baby
Putting Joey on this list is quite a tough lot. He mostly gets by in this show as the sweetest, most caring and nicest of all the friends. But, that's not to say his innocence and goofiness didn't ever translate into selfishness, with this being a prime-time example of Joey at his pettiest.
Huggsy, otherwise known as Joey's Bedtime Penguin Pal, was a subtle part of the show from season five all the way up to the ninth season. He was first mentioned in "The One Where Everybody Finds Out" and could be spotted here and there from then on. But, the adorable stuffed penguin became a problem once baby Emma came along.
In "The One With The Memorial Service", Rachel moved in with Emma, and she took a liking to Huggsy. This made Joey incredibly jealous, and he tried to switch the teddy out for a new one. Eventually, Rachel revealed that Emma missed the old Huggsy, and tried to convince Joey to let her have him. But, in the end, he refused and kept the penguin for himself - even revealing that he got Huggsy by stealing it from a child in the first place.
While it's understandable that you wouldn't want to give up a sentimental toy, surely Joey (an adult) should be willing to make the sacrifice for the sake of a literal baby.
