Although yours is a tad 'salty' of a limerick, it not as 'salty' as others I've heard in my checkerd past! Though not related to the subject of L.B.C.'S, it did remined me of a 'clean' little poem that my Pop would recite on occasion while working on his old Ford F-150:
A little spark.
a little coil,
a little gas,
a little oil,
a chunk of tin,
a bit of board,
put it together,
you've got a Ford!
My apologies to all you Ford owners!
...one mustn't criticize other people on grounds where he can't stand perpendicular himself. - Mark Twain
