A Shane
Bringing up a random fact like it's the end of the world, and then going on a 10-minute rant about it like it's a national emergency.
'Did I tell you my goldfish died last Tuesday?', Shane, during a meeting.
'I have 77 reasons why the sky is blue.', Shane, in the middle of a conversation.
'Why is the toaster in the fridge?', Shane, 3 hours into a random tangent.
