What is the stupidest argument tu ever had?

Oh wow, a hard one xD

I think the stupidest argument I had was with my BFF's brother, and he was being an mula as usual (he'd also busted my BFF's lip with his elbow, so I was pretty mad) so I started sassing him and he went off threatening me and stuff e_e I got lots more, but that was the most recent.

Me: *to self* that was so stupid of you!
Me: shut up! Was not!
Me: it so was!
Me: well, you're me, so it was stupid of you, too!
Me: was not!
Me: was too!
Me: oh, shut up!
Me: I'll shut up when tu do! We're the same person, remember?
Me: *shuts up* >:/

Had tons XD. My most stupidest one:
Me: tu spelled axe wrong! tu forgot the "E"
Friend: Dude, there is no "E"
Me: yes there is
Friend: no there isn't
Other friend: Guys, they are both spelled correctly...
Friend and me: *facepalm*
