Tunnel of synchronicity?

Carl Fink sent in the Loose Parts, which we supplemented with the Lockhorns on a similar motif.

Is it kind of charming that Loretta still has romantic expectations?

Carl says “So, let me ask this question: has anyone seen an actual ‘Tunnel of Love’ at a fair in the past, say, 40 years? Would anyone under that age have any idea what’s going on here? Is that old carnival attraction even remembered now only because of cartoons like this one?”

Also, what is going on? People keep climbing into those boats even though they can see the solid wall and the mounting crashes? Is it almost as much their incompetence as that of the designers of the attraction?
