IIRC in 'a voyage for madmen' one of the sailors was getting head butted by a whale and feared getting holed.
the best he could figure, the whale was sleeping or napping or whatever they do and he rammed it, scaring the thing into thinking it was under attack...
BEWARE THE NAPPING WHALE!! LOL. have a great weekend.
