I bet.
Fortunately I did comprehend the joke - but if you had used a better example to illustrate the comedic point - for example, "it would generate more lift than a C5 Galaxy", or even "a Jumbo Jet" then the hillarity-meter may have oscillated in a small way.
The advantage of applying such logic to the construction of amusing anecdotes is that it often has the added effect of increasing the longevity of the quip, perhaps even becoming part of common speech.
Another advantage is that the image of a Supra, with it's notably large arse, combined with that of a heavy-lifter aircraft is one that can further entertain the passing reader.
As an interesting aside, I wonder if anyone has considered fitting a delta-wing spoiler to the back of a Supra - at lower speeds the traditional wing-tip vortices found on straighter aerofoils actually exist along the whole wing - therefore may help with low speed cornering, and grip out of bends.
At higher speeds the lower front profile shape would exert lower drag, improving performance.
You may even consider building in the Concorde-like camber and twist into the delta - to further coax the elusive vortex effect during all conditions.
