Dum-dum Barney?
Some of my fave moments have come when Barney misunderstands.
When Fred & Barney were P.I.s
Dagmar: Are you fellas married?
Barney: No, just good friends.
When Gazoo zaps up Fred & Barney Nothing.
Fred: Thanks, Gazoo, that's terrific!
Barney: What's so terrific? Now there's four of us that can't go anywhere.
Barney: (shouting) Yeah, and maybe one of them is babysitting a sick friend!
Fred: Don't you know when to shut up?!
Marriage is between one man and one woman, to the exclusion of all others.
