Moody and Hagrid

I was listening to Moody's initial appearance in the great hall in 
GoF.  You know, where Moody comes in and we see his scars and magic 
eye.  When Dumbledore announces that Moody is a teacher, none of the 
students or the staff clap except Dumbledore and Hagrid.

Why do you suppose Hagrid claps?  Is it just loyalty to Dumbledore?  
We are told that McGonagal, Snape, Flitwick, Sprout and Sinistra are 
all present.  I would think that all of them except Snape would clap 
out of professional courtesy.  After all, many of them ought to be 
familiar with famous auror Moody's bizarre appearance, and they 
shouldn't be shocked the way the students apparently are.  

Or does Hagrid have a history of some sort with Moody?  Since I think 
we know that Moody will be in OoP (didn't JKR say this?), then is 
this some foreshadowing that Hagrid and Moody will work together for 
some reason in OoP?
