You could be part Mouser?
Here's a quick test to find out if there's a part of you that is Mouser. It'll take less than 5 minutes:-
Did you find Bread even mildly amusing?
In Bread, in the scenes that portrayed Joey going to the dole office to scrounge yet more money off the State, did you find yourself not so much laughing as taking notes?
Do you find yourself watching Top Gear to study the hubcaps?
Did Cilla Black form part of your earliest recorded masturbatory fantasies?
Are you stirred to tears when you hear Max Boyce singing "Walk On"?
When they play old clips of Gerry and the Pacemakers songs on re-runs of Blue Peter, do you find yourself trying to mimic the dance without a sense of irony?
Are you interested by Jimmy Tarbuck's golfing stories?
Do you get an erection when you see Liza Tarbuck?
If you answered "yes" to any of these questions, then either (a) you are part Scouse, or (b) you have Scouse syndrome. Either way, it would explain the alarming fact that you found Zingy's "joke" funny. The bad news is, however, that there is no cure for it.
