That's been a running joke with me for 20 years or more. I went to work one day and someone noticed my hands were all scratched up (I had been working cleaning up hedges in the yard)) and asked me what happened to my hands?
I told them I was circumcising my cat. Everybody just looked at me weird and I never told them any different.
Now THAT is a feat of bravado! You are a better man than I am, Gunga Din!!
