Wine or Grape Spray?

I recently saw an advertisement at one of our famous local supermarkets.  The advertisement is about value for money wine, but look at the Chinese character for 'wine', there is one stroke missing.  With the missing stroke, the Chinese character changes its meaning from 'wine' to 'spray'. 

Haha...It is good humour, but it shows our bilingo education still has quite a lot of work to do :)
