Thinking about yesterday’s post, I could’ve been more helpful.
The McDonald’s “real job advert” isn’t only a joining of two random ideas.
There IS a connection.
Can you see it?
It’s the word SERVE.
Once you spot this, you can immediately follow the gag’s progression.
You can serve Uncle Sam…
…but what else can you serve?
You could serve him a meal.
What kind of meal? (the real humour is in the specifics)
From there, it’s just a case of coming up with a McDonald’s equivalent of “see the world, travel to new places, learn new skills…kill people” list of benefits.
Once you have the SERVE connection, it almost writes itself.
Be on the lookout for words with double meanings. There could be an opportunity for a gag.
