Sam:  Dad what does vegan mean?

Scot:  That is someone who is a vegetarian, they won’t eat meat, but they also will not use anything that is made from animals like leather.

Sam:  What about farts?  Farts come from animals.

Scot:   Well, Vegans fart too because vegetables can make you fart.  But people don’t use farts for anything.

Sam:  I can think of some good uses for farts.

Scot:  I am sure you can.

Sam:  What does parallel mean?

Scot explained.

Sam:  I need an Otter Pop.  (off he goes)
