There's a guy who comes into our brewery, because he's an old brewer, and he's lost his mind a bit and lives in the bush.
He's always drunk and we try look after him and make the time for him because he's pretty unstable but ultimately a nice guy. However he's tedious, boring, irritating, and rambles on about things no one cares about. He annoys a lot of our locals by injecting himself into their conversations to talk about some garbage no one cares about for what seems like hours on end.
Bam and him are interchangable.
