Indeed, it just proves what I have always said - Dogs are dumb.
Cats are my choice of companion because they are quite capable of telling me to sod off and still have me love them - rather like the wife actually. The chimp obviously thinks that this sort of stuff is beneath him/her.
What creature of any intelligence would want to do what the average human wanted them to do?
Ah.....oh dear...... what have I said......"yes dear, anything you say dear"
