Any aerodynamicist will tell you it's flat out impossible for a bee to fly, yet . . . . they do.
The bumble bee analogy is very misunderstood and misused, and usually used to lampoon a perceived arrogance within the scientific community (deeply unfairly, in my opinion).
Rather than the claim coming from any aerodynamicist, it is actually usually attributed the French entomologist Antoine Magnan. The truer message is that bumble bees shouldn't be able to fly according to the aerodynamic models used at the time. This is due to limitations and assumptions within the model(s), rather than bumble bees somehow trumping the laws of gravity etc. If you feed observed data into your model and get poor results then it is time for a new model! There isn't a mystery to how bumble bees fly, it is simply that their ability to fly has been understood by degrees over time. Likewise the design of aircraft has been improved over time as well.
Dave is sort of like the 'Don Rickles' of bass dudes.
That is maybe taking it a bit far. Rickles is of another era, and I see him a bit as the "Fast Talking High Trousers" sketch from Family Guy. One of those entertainers that needed to be able to come up with quips very quickly, and always land on the mark. Britain had a bunch of comedians of that ilk in the '60s/'70s, and I always felt they had to learn their craft by punching their way out of trouble, verbally. These guys started in small, rough clubs trying to win over hostile audiences. My favourite Rickles clip is him on the Johnny Carson show making mafia jokes at the expense of Frank Sinatra, who is sitting there right next to him! Talk about balls of steel! He must have had to be in a fairly small group of people who could actually rip on Sinatra and get away with it. By contrast Dave just has to grumble away to a handicam for ten minutes at a time, with no hecklers etc.
Dave does the Cantankerous thing quite well, and I guess he has a good heart as he does work for free occasionally and I saw some charitable deeds mentioned in here as well. In general I don't like professional Youtubers, and I can see Dave falling into the trap of having to basically dial in this alter ego for every video to keep the view count high. I was a fan of 'Scott's Bass Lessons' for a while, until he fell for the trap of click generation by coming up with attention-seeking video titles and things. Why dilute the core value of your channel with banal "The Ten Things Wrong With 6-string Basses" or "The Top Five Licks Every Bassist Plays Wrong" or whatever? Likewise how much gas can Dave honestly have in the tank, before he becomes too smitten with advert revenue and decides he must fire out two videos a week, each of which just creeps past that magical ten minute mark, simply because his loyal fanbase enjoy watching him criticise guitars?
Rickenbacker fans are a bit like vegans; I hear more people complaining about them than I ever hear them complain themselves. There is a fringe nutter element to each group for sure, but Rickenbacker seem to be fairly unique in that it always seems to be open season for them on here, and the exact same criticisms get repeated as though they are new revelations. In general it seems to be that if you don't get on with Fender basses then the problem is
you, and if you don't get on with Rickenbacker basses then the problem is the bass.
