This could have worked really well if done properly.

Including a broken video link, briefly asking for help from the teacher before turning back and saying "Actually, let's make this a learning experience".
Slide 1: Linking Broken Videos.
"It's important when you use videos to make sure the video file exists on your thumb drive! If you're using YouTube links, then just double check the video still exists before your presentation and make sure to have backups. If you're linking to a file host it's always worth making sure you don't meet the free quota and have it blocked as a really unfortunate time".
Gesture strongly and drop remote.
"Whoops! Let me get that".
Slide 2: Dropping the Remote.
"So make sure you don't gesture too wildly when you're presenting. It can look pretty odd if you're flailing around"
Slide 3: Inflatable arm flailing tube man video (properly linked).
"Talking with your hands is good for emphasis, but make sure to be reasonable and use your non-dominant hand so you don't throw things at Suzie. Sorry Suzie"
Smile at person near where the remote fell.

If your presentation is about pitfalls to avoid in presentations then it could go down really well and could be seen as clever and funny. You have to have confidence to pull it off. Make mistakes, but be sure of yourself and make them a part of the presentation.

Sounds like OP was just trying to be funny and not clever, which can come across as awkward if the confidence is lacking. You might get a laugh during your presentation, you might not. Doesn't matter because every mistake made by anyone else will get a smile now. It simultaneously takes the weight off others for making mistakes and legitimises your presentation by making it appear relevant.

I say all of this as someone who had zero confidence in school and would absolutely not have been able to pull this off. Confidence is just a fake it til you make it thing. You will be awkward at first, but learn to laugh at yourself and it gets a lot easier.
