Why do we all misspell the word Bacon as BECAN as a matter of course?

For the same reason we say 20-40%, black dog, it's all crash in the loudspeaker, arse, ya and make parody threads (among other silly things). 

I should also note that most of the silliness has been going on for quite a while.  For example:

http://forum.cakewalk.com/Is-there-a-torrent-site-where-I-can-download-BECAN-m2126586.aspx
 
And, the earliest example I can find (so far) from September, 2010 where Ubiquitous Bubba mentions becan and JonBouy replies the next day.  Neither comments on the spelling so even this isn't the first use of it!

I just thought it must be because it stresses the essentiality of it. BE! And CAN! A rallying cry for pork lovers everywhere. Count me in!

Note that it does NOT have anything to do with the following!!!
 

Same applies to the term "Fred" It's not mine to question why it is. CH is as CH does

I stand for the right of individuality and the Coffee House epitomizes individuality. Where else are you going to hear this  THIS !  CH AS IS  FOREVER!!
