Dear Vince,

I'm sorry to hear about your trained rat!  Those are a lot of work to 
train and I'm sure you miss it.

I have it on good authority that there is a better way to run wires, 
Chickens!  They don't need training as they will instinctively run 
towards a light when they are shut up in dusty dark places.  All you 
need to do is position your assistant where you want the wire to end up 
with a flashlight, attach the wire to the chicken (staples?) and shove 
the bird above the ceiling.  A few minutes later the wire is quite 
literally "run".  No special training, any old chicken will do!  Once 
they wear out, get a bad attitude or try to unionize you can have 
chicken stew for supper!  Truly a win-win situation.
