"You know Ice Man, right?"
"Ice Man. Like, the superhero."
"Well, he goes around by making ice, and he rides along it. What happens to all the ice? Like, is there ice left all over the town?"
"It probably melts."
"Oh, true. But it would be a problem if there was, like, an evil villain person who wanted to catch him, he could just follow the ice... I suppose it's a good job it's ice, though. There must be a whole load of superheroes who have it worse, like... Fondue Man... can you imagine, having to ride along on a wave of fondue, and leaving it all over the place? Imagine the smell."
"Imagine the rats!"
"Oh, I think the rats are his sidekicks, and they solve problems for him, like the cat in Hong Kong Phooey."
CHECKOUT PERSON: So, that'll be £16.48.
MARN: (long pause) What happened in 1648? I thought it was the Spanish Armada. But that sounds like it should have been in 1548.
CHECKOUT PERSON: Yeah, that's definitely the Tudors. It was under Henry, wasn't it? The Mary Rose and all that.
MARN: I thought it was Elizabeth. Didn't Philip of Spain send the Armada because he wanted her to marry him?
CHECKOUT PERSON: Well, what you've gotta remember is, Spain as such didn't exist at the time. There were, like, two or three different states there, and then you've got the Holy Roman Empire making things more complicated...
(discussion continues for a while)
More of this, please.
Old lady: And they rearrange the shelves all the time.
Guard: They do it on purpose. To see if you're awake.
Old lady: Well, I can never find anything.
Me: You know, it's to the supermarket's advantage to have you wandering around looking at the shelves.
Old lady: Well, it doesn't work with me. I just say (lowers voice) sod it, I'm leaving, I'll do without.
Me: And the world needs more people like you.
Guard: Yeah, everyone buys too much stuff, more than they need. And then they throw it away instead of giving it to the homeless.
I left them discussing practical socialism.
