Hope that's helped a little.I've just watched a sketch by The Two Ronnies entitled Crossed Lines. I understood annoyingly little of it. Could you please help me? The video is here.
At 1:10, Corbett says, "Bloomers too large." What did he mean by that? I know bloomers are a kind of underwear and that makes it a joke, but he was talking about something else, right?
Yes he was. He's going through a list of things he tried get at Sainsbury's (a department store).
Bloomers (2, large). I'm not sure what this British idiom is. It could mean flowers - 2 large, blooming flowers.
At 3:05, he says, "I thought it said 'Oxo'." What does it have to do with a cross-your-heart bra? What does "the opportunity to have a quick butcher's" mean, and why is it funny? And again, what does it have to do with Oxo?
I believe "a butcher's" = "a butcher's hook" = "a look" in rhyming slang. The opporunity to have a quick look.
OXO is meant to be a visual symbol for a cross-your-heart bra. I can explain further if necessary.
What does a dog leaping into someone's lap have to do with apples?
Not sure about this. I think it was just a transition setting up for a few more gags.
At 3:53, what's the joke about? I understand he's talking about apples when he says "Cox's Pippins". I think the joke is that it sounds like something else, but I'm not sure what. I can't come up with anything that sounds the same and makes sense. "Cox's" sounds like "cocks his", but that doesn't ring any bells. Is it a sex reference?
The dog jumps into your lap and cocks his pippins. This is the Two Ronnies. It's almost certainly a sex reference of some sort, but I'm not sure what "pippins" are (apart from apples). If you've got a weird enough mind, it probably doesn't matter.
