Are you trying to communicate ?

One of the bosses of the main company I work for came in the office this morning to greet us ; he noticed my Slackware tee-shirt.

him : oh, you’ve got a pingoo !
me : no, it’s a Tux…
him : a Tux ?
me : a Tux !
him : ???
me : Tux is the name of the pingouin that symbolizes the Linux operating system
it’s a free, both as in free of charge and freedom, operating system
When it smokes Bob’s pipe, it’s the Slackware Tux. They all have a different way to
draw it
him : I know what Linux is, do you use Linux at home ?
me : I used to, but I’ve switched to OpenBSD… it’s for people with a bigger beard !

(he publicly made fun of me the first time I had let my hair and beard grow)

Next time I’ll bring chunky bacon or a gorilla at the office…
