Plot Outline:
After reluctantly inviting socially inept neighbors Fred and Mary Ellen Doyle ("Cheers"' John Ratzenberger & Shelley Long) and their kids over for dinner, Paul and Cate are shocked when the entire Hennessy clan is asked to take part in the Doyles' daughter's wedding. Meanwhile Kerry neglects to inform Bridget that geeky Donny Doyle (Thad Luckinbill, J.T. Hellstrom on "The Young and the Restless") has grown up to be a hunk, and Rory takes a part in a play as a cross-dresser in order to meet girls. Cate (Katey Sagal) sings the jazz classic, "At Last," at the wedding reception.
