Apparently Dinkle, who’s obviously spent way, way too much time hanging around that school, has no idea how actual tunnels work. And apparently TheAuthor, who’s spent way, way too much time re-visiting one of his old Act I stalwarts, has no idea how to make Dinkle funny without invoking his old, long-since dead and buried persona. Or even when he does, as aptly demonstrated today.
Of course the one glaringly obvious flaw in this “joke” (other than the aforementioned tunnel fail) is that Dinkle, who apparently NEVER leaves the school grounds except for infrequent sex romps and massages, must have seen the big inflatable football helmet before. But for the sake of his creepy fantasy, the reader has to pretend this is the first he’s heard of it. OK Tom, whatever. Like I always say, no point in having suddenly start making sense now.
