Rugrats (1991)

Season 2: Episode 16

After 40 years, Grandpa's long-lost love Morgana pays a visit. Morgana broke up with Grandpa over his affair with another woman named Trixie McGee, but never knew the real story. Also, Grandpa doesn't want her to know that he's a grandfather, so he rushes Tommy and Chuckie to bed. In any case, everyone has to contend with Stu's new remote-controlled couch, which is more like a mechanical bull for two.
