Yeah you need to make an iframe where you want the content to appear, and then edit the hyperlinks target so it is the name of the iframe.
As Tom said, give google a searh for iframe.

When you search for me you get a photoshop job I did in IT in year 11 to piss off my old maths teacher (He is Welsh, and is a runner, so I made that and then put it up on his running club website)
He died.
I don't think he deserved to die to be honest.
EDIT: Ok Tom-Ass changed his story, apparently he didnt die, but if he did he definately didnt deserve it.
Can't you just take the wheels off and say its broken so you brought it in to fix it? Or take a few bits off like b/s and wheels, and say its bike parts like Dave said?
