Pronouns like “myself” and “himself” can also be used to add emphasis to a sentence, and when they are, they’re called intensive pronouns—same words, just a different name because they're used differently.

For example, if you witnessed a murder, you could say, “I myself saw the madman's handiwork.”

but when using it, do I say myself do or myself does?
(Google doc is auto correcting my "myself do" to "myself does", hence I'm confirming)

So, what is the correct way to say it,

• I'll make sure me myself taste it for you.
• I'll make sure me myself tastes it for you.
