What moves can Mew not learn?

Question

Mew can't learn certain moves such as Hydro Cannon, what are the other moves Mew cannot learn?

Mew can actually legitimately learn both Pay Day and Bubble Beam in Generation 1. TM 11 Bubble Beam is your reward for beating Mysty the second gym leader of Red and Blue. TM 16 Pay Day can be obtained in Red Blue and Yellow on Route 12 south of Lavender Town. Surf is required to obtain the TM. Oh almost forgot TM 34 in Generation 1 which is the reward for beating Brock is Bide. Apparently Mew can also learn Curse in Generation 2 via TM 3 which is located in the Celadon Condominiums where you get the Tea item in Firered and Leafgreen.

Oh can't forget about TM 24 which is Dragon Breath in Generation 2 which is given to you when you kick Clairs' butt. Dragon Rage is TM 23 in Generation 1 which is purchased at the Game Corner for 3300 coins. Damn yet another mistake. TM 37 is Egg Bomb in Generation 1 Red Yellow and Blue. It is found laying on the ground in the Safari Zone or can be purchased for 2000 poké at the Celadon Dept. store.

Okay you get the point now. If you took the time to look up your answers yourself you'd know TM 27 in Generation 1 is Fissure which is obtained by beating Boss Rocket Giovanni during the final gym battle. TM 49 is Fury Cutter in Generation 2 and is given to you by Bugsy. There are probably several more mistakes in the answer you accepted but its 4AM right now and I'm tired of fixing their mistakes.

You made several mistakes with your answer. I took the liberty of fixing some of them. Next time do your research before you answer a question.

@Akuma625
What exactly are you referring too? You have not done any liberty of fixing the answer, nor do you have the ability to do so. Unless of course, you're probably referring to an answer you have posted that has yet to be approved by a mod.
Edit: Yes, this seemed to be the case

It is another thing though, to accuse a user for not doing their research on a post last updated 4 years ago.
Edit: I see I was wrong

Approved it, sorry for the couple hour discrepancy with this. I moved the post to a comment because it does not answer the question alone.

You probably already saw this but here's what I fixed.
