The One Where Rachel's Sister Babysits - S10-E5
Corrected entry: No piercing studio in the world would pierce the ears (or any other body part) of a one year old without consent of the parents.
The One Where Rachel's Sister Babysits - S10-E5
Corrected entry: When Joey uses the thesaurus to write his recommendation letter to the adoption agency, he signs the letter, "Baby Kangaroo Tribbiani." While certainly comic, and even though the word "joey" does mean "baby kangaroo," it does not come up in the MS Word thesaurus (and it was strongly suggested that they were using Word, as they referenced the thesaurus being under the Tools menu), nor does www.thesaurus.com correlate the two.
Correction: Most software has a Tools menu so it's not reasonable to assume that it could only be MS Word.
Correction: It's true that piercing studios will likely require consent, but if Amy just said, "this is my daughter," I doubt they'd have a policy of requiring a birth certificate or anything.
