Do you know how many types of melon there are? No?
Neither do I, but I know the Cantaloupe melon variety, which is what I had for breakfast this morning.
With its lovely bright orange colour inside, it's sweet and juicy and lends itself to "silly" joke-making in English, like the example above. To lend itself is an idiom that means to be suitable for something.
The watermelon asks the melon to marrying him but she says she "Can't elope". It's a play on words. A cheap but useful one.
Do you know someone who has eloped with their lover?
The verb elope is used when two people want to run away secretly in order to get married. Unfortunately, this marriage between the Watermelon and the lovely Cantaloupe is not meant to be.
Yeah, I know it may be a sad joke, but... we still explored the nature of the English language, which constantly lends itself to jokes such as these.
And by the way, did you know that this kind of association is a good way to memorise new vocabulary?
So, how many silly jokes in English do you know? Why don't you share them here so everyone can learn from you?
