IIRC There is a lion model in Poser. From which you could use the head. I

He should have thrown one just to try :p

LOL after I saw the piano explode in fire, I expected to hear the car play a
chord :-p
It looks like what we called "Couillard" in middle age France
http://medieval.mrugala.net/Armes%20de%20siege/Couillard.htm
Don't ask me why it is called couillard . I'll just say that  our "couilles"
are like your bullocks (but bigger of course ;-)

Thanks Mark
In that case RusHHouR, you might be able to export only the head or delete
the body in Poseray. Assuming you downloaded it.

You are right and I cannot imagine that throwing arm surviving the
sudden stop when it hits the massive top beam .

Not a practical design at all

Well, that's only a Hollywood myth.  In real life, pianos usually do not
explode on contact. ;-)

That's not a catapult but a trebuchet. Same purpose but completely different 
principle!
A catapult use tortional or flexing (bow like part) force.
A trebuchet, as in the clip, use counterweight.
Usualy, a trebuchet have greater range and can trow heavier projectils, but 
takes longer to reload and fire. It also frequently have poorer acuracy.

You may not know this but many nonliving things have a gender...

A Hot Air Balloon is Male, because, to get it to go anywhere, you have to light 
a fire under it, and of course, there's the hot air part.

Thanks, I made that about 10 years ago before I even knew about macros in
POV a lot of cut and paste and editing coordinates to place the detail just
because I was too lazy to read the manual about macros... Nice video clip
BTW

Yes, you're right. I actually tried painting a HF image in Photoshop
to try and re-create your lion's head...but finally gave up in utter
frustration. Not as easy as it looks!!!
