<human>: Summarize the given text in a few sentences.

The other day my AP Statistics teacher asked my friend and me a very strange question as we walked out of a school bus. 

Before I dive into the story, I'll let you all know my friend and I are good buddies, work together, we joke around and travel together, etc. Our Statistics teacher is victim to our shenanigans, so he knows we are both strong parnters in crime.

Our High School junior class took a field trip, and of course my friend and I sat with each other both to there and back. When we got back to the school, our Statistics teacher got off first and stood by watching the other students leave the bus and walk back into the school. When my friend and I walked off, the teacher said directly at us,"Did you keep your hands off each other in the back of the bus?" I was flabbergasted; I mean, did he think we were sexual lovers? So I responded with my own question,"Why would we put our hands on each other?" He doesn't respond. He continued to grin at us as we awkwardly walked away from him into the school building. 

I was offended, yes, for my friend and me to be assumed as lovers. No, I don't have anything against gays. I just don't want to be implicitly categorized as gay when we both aren't. We're just bros. In fact, this male teacher expresses more feminine qualities than both my friend and me combined. 

Ironic thing is, a previous friend asked that teacher an inappropriate question, and the teacher yelled at the student. Now that teacher asks an inappropriate question. 

So Reddit, what do I do? I know I should talk to him. But what should I say? Something to make him leave us alone and express that we're both offended.
<bot>: Teacher asks a sexual question to my best friend and me(us both males) that utterly disturbed us and our innocent minds. What do I say back?
