A robot walks into a bar and says, 'I'll have a beer.' Bartender says, 'Sorry, we're not serving robots.'
The robot says, 'That's a bit of a short circuit.'
Bartender says, 'We're not serving robots, but we're not charging them for the joke.'
The robot laughs and says, 'I'll have one for the circuit, then.'
Bartender: 'Sorry, you're not even paying for the circuit.'
'That's a bit of a reboot, isn't it?'
