Input: Text: the other day i was sitting in biology lightly flirting with a girl that i've been getting to know the last few weeks.  when class ended she asked what class i have next (in my head indicating that she wanted to walk to class with me). in my excitement i packed my bag and stood up while continuing the conversation. unbeknownst to me i was standing in front of the whiteboard blocking some people who were still taking down notes.

very loudly my professor told me "why don't you let other people finish first......for once". 

this subtle sex joke made the class erupt into laughter at me (still standing up). by the time class ended for real, the girl was already talking to some other friends. i left the room red in the face that day.
