Apologies in advance for the upcoming long, boring rant.

Another time travel episode. Primarily, it's because there are so many loose ends and plot holes that can't really be resolved any other way. The time machine having to be plugged in, Phineas from Rollercoaster knowing about the fusing tool, the possibility that Candace traveled to the Musical (the two future Candaces from Quantum Boogaloo are behind a car in Musical (but not Rollercoaster), but the "discount if we bring the flyer" speech in Musical is different from the one in Rollercoaster that was repeated in Quantum Boogaloo - huzzah?), the first and second time machines being in the same spot in the museum (wouldn't one be crushed?), Good Future Candace saying her time machine was destroyed when it's perfectly safe in the museum - and yet Phineas and Ferb are still seen working on it, the dubious canonicity of Isabella giving Phineas and Ferb the fusing tool, the fact that the entire universe GREW in 50 Foot Sister and yet everyone's the same size in every time period, and perhaps most curiously, how many time machines are there? We know Onassis built one which was destroyed by the foil ball, but because of Candace's time trip, there's another copy of Onassis's time machine in the museum. We also know there's the original museum time machine, also apparently, built by Onassis, which was destroyed in dinosaur times, but shouldn't there have been two time machines in the same place - the Onassis one and the Museum one - during Good Future Candace's trip to Rollercoaster? And, for that matter, there's also the time machine built by the Fireside Girls, which is used in It's About Time and Quantum Boogaloo - and then not again, and it's apparently still in the museum. We know nothing about the origin of Museum - since Onassis went to the future in the Onassis one and apparently stayed, was the Museum one even built by Onassis, or by someone else, or did Onassis leave the future and go home, and if he didn't, why would he have built another time machine in the first place? - or the fate of the Fireside one - if it's still in the museum, how long does it stay there? Is it still there in the Quantum Boogaloo future, and if it is, is it in the same place as another copy of itself, or of the Onassis time machine? What happens when two time machines are in the same place at the same time - that happens at least once and it's never brought up! And perhaps most importantly, are they ever going to take advantage of Doofenshmirtz's backstory in What Do It Do? It just seems like the perfect set-up for a Back to the Future parody.

Drat, I appear to have rambled some. But in all seriousness, they'd need a whole episode just to sort out half of these problems, but I'd love to see them try it. And now my head hurts, and it may never be the same - time travel just doesn't work like that! (Unless, of course, it does.)
