Neither will a tomcat or a penguin.  I mean, they can be made to fit, but they clog the 
ventilation channels and that leads to severe overheating.
Chuck's stick option is interesting however, and I'll bring it up at the next hardware 
planning meeting.
To get back to hamsters, contrarily to what you assert they are very diligent and fast, 
and they compensate their limited memory with their built-in storage and pipelining 
capabilities; they easily fit into server racks (specially our Roborowskis), and they have 
a few other logistical advantages : they do not generate a lot of heat, so we don't need 
expensive cooling systems; their lifetime approximately matches those of Intel chips, so 
we haven't had to buy new processors in the last couple of years : we just breed them. 
This way we have a natural permanent upgrade process, with always at least 33% 
last-generation processors.
Their one real inconvenient is that they look like mice, so we have to keep them separate 
from our tomcats. But for that we use separate racks, with mod_jk connections.
