This is funny to me....

Why is it that once again it always has to be about 'dropping' and 'teaching him a lesson' and 'my mom's better than your mom'....

We really can't help ourselves can we?
It's amusing when you step back and look at it from afar.

Anyway, having said that, what do YOU really want from this?

It sounds to me like you're not sure.
If you really are not interested in the guy or spending the time on it, well then for cryin' out loud be a man and just tell him that.

If you look down inside and admit that you too are curious about it, then grab the bike you can perform best on and just go ride to see what comes of it.

If indeed you look even deeper and feel the need to make this some sort of personal proving ground (ala the Knave chronicles) then go out there, start a ride with him at a reasonable pace, and just keep picking it up until you've got a hammerfest going.
