A selection of headlines from stories in the news. They use English in a way that you might think is intended to confuse but it's all perfectly clear to the native speaker.
This headline in the Sun is for a story about children falling asleep in primary school lessons because they are playing computer games until 4am, basically they are so tired, they falling asleep at their desk.
It's a play on the game console the XBox, substituting Zzzz which is often used to show that someone is asleep and snoring. Sometimes we say things like, "I need to catch a few zeds," which means I need to get some sleep.
