Question

How would your hook be if your topic was about the super hero Mario

Answer 1

You should start it with all of mario's catch-phrases such as it's a me Mario or Let's a go

Answer 2

You could start with:
"It's a-me, Mario"
and switch out Mario for your name
Lets say your name is Juan (for example)
Then, your hook/grabber would be:
"It's a-me, Juan"

Hope it helps
If you need more help, just holler! :)
