I say Tomato - you say Tomoto!

So it was pretty funny today in the office --

I knew all the British say Tomato like Tomoto...with the ''O'' sound.  So I asked the question...do you say Potato or Pototo? HAHAHA

Did this cause an uproar of laughs - of course they say Potato the normal way like I do.  So then I said - ''Why do you call it Potato and then Tomoto - they are the same?  You have to pronounce them the same - otherwise it sounds silly.  Fun times!  My co-workers are all really fun and nice!  Makes going into the office enjoyable
