Does SMG3 hate SMG4?

I've been noticing a lot of tension between SMG3 and SMG4 in recent videos. It almost seems like there's some sort of rivalry or dislike going on. So, does SMG3 really hate SMG4, or is it all just for show? It's hard to tell with all the jokes and sarcasm flying around, but it definitely seems like there's something there. I'm curious to know what the real story is behind their relationship. Could you shed some light on the situation?
