A pony walks into a bar and says 'Bartender, may I have a drink?'
Bartender says 'What? I can't hear you. Speak up!'
'May I please have a drink?'
'What? You have to speak up!'
'Could I please have a drink?'
'Now listen, if you don't speak up I will not serve you.'
'I'm sorry, I'm just a little hoarse.'
