Lisa Kudrow’s Phoebe wasn’t dumb, she was hippy-dippy. She was Jenna Elfman’s Dharma with added daddy issues. Rachel has a certain rich girl naivete to her especially in early seasons, but the outright stupid one is Joey. Phoebe is a functioning adult that holds down a job and pays her bills, Chandler tries to teach Joey how to pay a phone bill.

The show didn’t have ten seasons in it; hell season ten is short, and by season six I swear there are episodes that are almost entirely catch phrases. “Nooooo.” “I know” “WE WERE ON A BREAK!” then Janice walks in and nasals out “OH. MY. GOD.” I bet you could cut together a coherent episode like that, The One With All The Catchphrases.
