grade 11 Social studies... "we have to stick something in the dykes hole to stop it from leaking" it was totally in a different context, but of course me being the immature kid I was (am) just burst out laughing along with a few others.
Also in grade 11 I was arguing with my math teacher about a test (fire alarm went off so we lost 20 minutes) and I got all mad and was like "this is bullshit." well he told me to go talk to the department head, and as I was leaving the room he yelled "make sure you tell her that it's bullshit". It was funny because as he yelled that, the department head was walking by and heard him, and gave him the weirdest glance.
ok after typing those I guess they are both not funny unless you were there, but whatever.
