high school students have dirty minds : )

In my high school class we are playing a beatles medley. Today we were working on it and after we played through it once i said "lets try getting into Michelle"....as i learned today, this is not a good thing to say to high school students...so the whole classes started laughing and i turned to the girl who started the laughing and told her she had a dirty mind and then she told the whole class that "she was hungry"....which of course brought about much more laughter. I think teachers are not supposed to laugh at stuff like that but i just can't help it...i was laughing just as much as my class. : )
