Exchange in a Sheps pub last night, which had four of their ales available-

Customer: 'What's the Whitstable Bay like?'
Barman: 'It's Shepherd Neame so they all taste the same'

The barman went on to explain that he doesn't like Sheps beer: 'I don't drink it - I only look after it'

Perhaps unsurprisingly, they did all turn out to be pretty much the same.
