I'm watching Cougar Town as didn't watch it at the time (blame lock down boredom) and Matthew Perry and Jennifer Anniston have made appearances (as far anyway) but I remember when Joey started it was hinted that Friends cast would make appearances but never did.
Does it mean that Courtney was preferred over Matt le Blanc or was Cougar Town just a better show?! It did run for 6 seasons whereas Joey was only on for 2 and I think pretty much panned.
