A teacher friend of mine said that the worst present she ever received from a child in her class was a pair of tights. Another said that she once got a bottle of wine which had been opened and 1/3 of it drunk. I'm not starting this thread to have a dig because, believe me, with 2 DCs getting the teacher a present at the end of term can be a bit trying, but some stories I hear are hilarious.
Sorry, there might be a thread about worst presents in general, but some teachers' stories are just corkers.
