4x23 - That '70s Show

Kitty plans a surprise birthday party for Hyde's 18th birthday. She recruits Jackie and Fez as decorators because of their feminine creativity (much to Donna's annoyance). Eric, Donna, and Kelso decide to steal a street sign for Hyde's present. But Hyde doesn't want to celebrate because he thinks this means he'll have to move out of the Formans' house.
