Three's company: Season four

Jack on the lam

Love thy neighbor

The new landlord

Snow job

Jack the ripper

The life saver

Old folks at home

A camping we will go

Chrissy's hospitality

The loan shark

The love barge

Ralph's rival

Black letter day

The reverend steps out

Larry loves Janet

Mighty mouth

The love lesson

Handcuffed

And baby makes two

Jack's bad boy

Lee ain't heavy, he's my brother

The root of all evil

Secret admirer

The goodbye guy

Jack's graduation.
