At the moment I work at a school/after-school daycare, more specifically I work with the 1st to the 3rd graders at the local school, and these kids does quite often come up with some statements making it hard for us that work there to
keep a straight face.
Here are some that I remember right now (names are changed to protect the uh... innocent):
1.
2nd grade boy(notice: his mom is a medic or something): Sarah, how old are you?
Sarah(a co-worker of mine): *sips coffee* 46
Boy: How many children do you have?
Sarah: One
Boy: Oh, didn't you have anymore sperm-cells?
Sarah: *chokes on coffee*
Boy: My parents had two. One became me and the other was my brother....
x3 he's so (mis)informed it's scary sometimes ^^;
2.
2nd grade boy: *some complaint about some girl(s) bothering him*
Teacher: *basic question about exactly what happened*
Boy: she hit me in the spinal cord
Me and another teacher-assistant: O.O *turns away while trying not to laugh out loud*
I pity the teacher that had to keep a straight face while talking to that boy and solving the situation ^^;
There have probably been more periods like these, but right now I can't seem to remember them XP
