Just hit the spider...

During the last few minutes of class, the class is having a discussion about learning to play baseball as kids

Teacher: I only found out about a week ago that I've been batting wrong all my life, because we never had coaching like you guys do. We'd just go out on to the feild and figure out what we were supposed to do.
Student: You're supposed to hit the spider, remember?
Teacher: *gives student a weird look* What?
Student: You know. Like, when you're hitting the ball off the tee-thing, you're supposed to hit the spider.
Teacher: *getting irritated* Well, nobody ever taught me to hit the damn spider!
