Truly odd graffiti has left Melbourne residents completely baffled.

The vandalism in question keeps urging someone called Chris to call “before the baby is born”.

“Chris u need 2 talk 2 me B4 baby is born or dont (sic) bother after (sic),” one piece reads.

Similar messages are scrawled on walls, pavements and public barbecues around the city.

Chris, mate. Just give her a buzz.
