When Gary tells Rhoda at the Costume Shop he wants her to go shopping for underwear for him:

Rhoda: He wants me to buy his underpants!
Ramon: How much does he want for them?

:lol:

That is why his presence was missed in Season 5. Along with Gary, and hell even Johnny Venture was missed if you ask me. They gutted a lot of cast members we got to know.

The biggest difference in the show's dip in quality between Season 4 and 5 was that Alan Katz and Don Reo were involved in the show in Season 4 but not in Season 5. They came up with the best Season 4 scripts and when they were gone it was all over.
