How can I be "beside myself" with whatever?

Do you ever hear a common phrase and are struck by just how odd it is? How can I be "beside myself" with some feeling or other? Where did it come from and are there any others that make little sense?

  • I was a trades store-keeper and the men were always joshing me, such that when they were serious I didn't believe them. One of them asked me for a, mouse' and I laughed, until one of the electricians explained this was a flexible tube used to pull cables through. I was asked by the surgery team to borrow the bolt croppers; I also thought this was a joke, thinking they were going to use it on bones! They were using it on a recalcitrant bolt on the operation bed. But I did have fun discovering about obscure tools and items and enjoyed this part of the work.
