Make funny questions and do like a little skit after each one. If you want, check out my first YouTube video, it's a Q&A, and I add in a little funny clip after almost every question. You don't have to do this but people find that funny.
Also, when I did that video I asked my friends for the weirdest questions they could think of. Be sure to ask your viewers/friends like the previous people stated!
I hoped this helped! Thanks!
Also, nice channel!
