And in the comment section tell us about what you think makes a good PowerPoint or what doesn't work at all [or] PowerPoint. Or even better, the worst PowerPoint you ever seen. [Let's saw] the comment, leave a link. I wanna see it. ... Wow, nice..., oh, I [or I've] told you over 500,000 times I don't take milk in my coffee.

Could you help me with the text in red?

In item 1, he does seem to say "or" although it makes no sense. But "or" is all I can hear. The second one is a muttered "Let us know in the comments." In item 3, I'm pretty sure I can hear "I've" although it could be just my brain playing tricks, since I know it should be "I've." In just the same way our eyes can deceive us into seeing things that should be there but aren't.
