here's a bad joke

This guy goes to a bike store and he's looking around the floor of the store, just kinda wandering around aimlessly with a focused look on his face, brow furrowed. A woman working behind the counter notices him and after a while she says, "can I help you with anything?"

The man looks up and says, "All these bikes are already put together. I want to build my own bike. Do you have any spare parts?"

The woman says, "Yes, sir. As a matter of fact, if you'll follow me to the back, I think we have just what you need."

The woman goes to the back of the store and opens a plain wooden door and the man follows her into this unfinished back room. Inside are a ton of bins full of random bike parts in various stages of disrepair.

The man walks over to one of the bins and fishes out a pedal. He holds it up and says to the woman, "Now, I've never built a bike before. Heck, I've never even ridden one. I barely know what I'm doing. Do you have anyone that could recommend the right set of pedals for me?"

The woman says, "No, we don't have a pedal person."

The man sets down the pedals and says, "Alright."

He picks up some handlebars and says, "Anyone work here that could tell me what to look for in handlebars?"

The woman says, "No, we don't have a handlebars person."

The man sets down the handlebars and picks up a seat from another bin. "Could anyone tell me how to pick out a proper seat?"

The woman says, "No, we don't have a seat person."

The man drops the seat back into the bin, getting a little frustrated. He walks over to another bin and pulls out some brakes. He looks at the woman and says, "How about brakes?"

The woman says, "No, we don't have a brakes person."

The man picks up a frame and says, "How about a frame?"

The woman says, "No, I'm sorry sir, we don't have a frame person."

The man drops the frame and brakes and fishes out a set of gears and chains. "What about gears and chains. Do you know anyone that could explain what these are and how to attach them and use them properly?"

The woman scratches her head and says, "No, I don't think we have a gears and chains person."

The man picks up a wheel and says, "Can anyone tell me what this is and how to put it on a bike?!"

The woman says, "Oh yeah! I can help you there. I'm the spokesperson!"
