When Niles (David Hyde Pierce) partners up with someone other than Frasier (Kelsey Grammer) for their club's squash tournament, Frasier teams with Chelsea Gray (Jeanne Tripplehorn), a sexy phys-ed teacher. At the end of the tournament, Martin is delighted that at last one of his sons has won a trophy -- but the other son, Niles, is not. As for Chelsea, Frasier wonders if his lifelong terror of P.E. instructors will ruin his chances at romance. This is the classic episode in which actor Bob Hoskins repeatedly materializes on the shoulders of guest star Jeanne Tripplehorn. ~ Rovi
