It makes it more amusing and more random...
Like I was talking to dp yesterday about some books that I had been reading, I said that as I had read 3 or 4 by the same author they were becoming a bit "samey" to which he replied, well play the sausage and mash game"
Cue much confusion from me, but apparently you replace every word that begins with an s with sausage and every word that begins with an m with mash... YEAH OK THEN!!!!
still it wouldnt come close to the random-ness of this thread
