THE GUEST Mandy Patinkin

THE CHARACTER Hugh St. John Alastair Parkerfield (from ''Lisa's Wedding,'' 1995)

The Princess Bride star could reprise his role in a second movie as Lisa's future fiancé. We're thinking a flash-forward scene where Homer has a score to settle with the pompous Brit for his refusal to wear those adorable piggy cufflinks at the wedding: ''Hello, my name is Homer Simpson. You dissed my piggies. Prepare to die.''
