4 - 6: Apologies for the Frivolity

Charlie is dating a new woman, Lydia (Katherine LaNasa); her attitude is exactly like his mother's. After introducing her to Berta, Alan and Jake, they can all see it, but Charlie still cannot; Lydia and Berta do not get on well with each other. Title quotation from: Bobby the waiter, after being scolded by Lydia.
