Til the Next Goodbye

S7, E25: Red and Kitty explode when they discover the guys smoking pot in the basement. Eric finally leaves for Africa, but not before he can get a hug (and a penknife) from Red, declare his love once again for Donna and survive a leaving party organised by Kitty. Later, Hyde turns up in Chicago to get back together with Jackie - only to discover she's just had sex with Kelso.
