Arrested for laughing

This is from an actual trial in the UK:

A young woman who was several months pregnant boarded a bus. When
she noticed a young man smiling at her she began feeling humiliated
on account of her condition. She changed her seat and he seemed more
amused. She moved again and then on her third move he burst out
laughing.

She had him arrested. Then the case came before the court, the young man
was asked why he acted in such a manner.

His reply was:
When the lady boarded the bus I couldn't help noticing she was
pregnant. She sat under an advertisement, which read: 'Coming Soon: The
Gold Dust Twins'.

I was even more amused when she sat under a shaving advertisement,
which read: 'William's Stick Did The Trick'.

Then I could not control myself any longer when on the third move
sat under an advertisement, which read: 'Dunlop Rubber would have
prevented this accident.'
