Wolf spiders aren't really dangerous. They're just very large and fast.
I recommend using them for pranks. Gather some bait (live insects will do) into a jar and wait for one of the spiders to come. Cap the jar and find a friend. When he's not looking, open the jar and dump the spider right on his head. He'll sure be scared, but it'll all be laughs when he realizes that the spider isn't from a family typically known for dangerous bites. Practical and fun!
