Everest. Any time he is bored I see him Mount Everest.
A horse made by committee.
Nine. One to do the shoeing, and eight to lift up the horse!
You can't cross a scalar and a vector.
He really wasn't feeling up to it.
Have a rest. (Everest, get it?) Really awful joke, but I thought of it last night and was wondering if anyone recognised it? Who knows, it might be original....
