That '70s Show - Season 5 Episode 15 -

Donna's dad Bob and his partner Joanne are off for the weekend, so they plan a weekend together, but the gang is determined to throw a party there, and unforgiving when they really refuse it. A call from the jeweler makes Kitty think Eric's engagement ring for Donna is for her, but she finds out while taking 'poor orphan' Hyde shopping for a new coat, which turns out an Evis-flashy jacket, yet tries to help preventing Red finding out, but the next paternal tirade makes Eric spill the beans himself.
