@@smill1985 Yeah it's true. They were in Coneheads. Unlike Houseguest, Sinbad and Phil Hartman's characters never shared any screentime in neither Coneheads nor Jingle All the Way.
I wonder, why did Sinbad have to come up with different things for what GFH stand for, what's wrong with him telling them all it stands for: "Gaming Foundation of Harlem"?
