The announcement yesterday of Samantha Cameron's pregnancy was a gift not only to Conservative Party spin doctors in the run up to the general election, but also to newspaper sub-editors.
Here's today's headline from The Sun: 'Wham bam! Sam Cam to be mam - and she'll need a new pram'.
While the Daily Mail went with: 'Sam's having a babycam'.
A more political - and less alliterative - approach was taken by both The Guardian: 'Sam Cam's labour bombshell', and The Times, with: 'Sam Cam moves towards labour'.
Puns are often regarded as a pretty low form of word play and usually elicit groans rather than bellows of laughter. For a pretty thorough analysis of puns and various other types of wordplay click here.
However, constrained by space and the need to catch a reader's attention, tabloid newspapers have raised punning to an art form. I never buy or read The Sun but I have to admire the skill and audacity the paper's subs display. The Sun is the Daddy when it comes to the fantastic headline.
Here's a few examples:

Freddie Starr ate my Hamster (13 March 1986) (I know it's not a pun, or strictly playing with words - but it's a monster headline)
