Anyone who has been to Australia knows, don’t mess with customs folks.

A Czech man who allegedly tried to smuggle 16 bird eggs into Australia by hiding them in his pants has been charged.

The 39-year-old was frisked at Sydney Airport by customs officers after arriving from Dubai on Tuesday.

“Officers … allegedly found 16 small eggs concealed in his groin area,” Customs NSW commander Tim Fitzgerald said.

Government vets are trying to identify the species of bird.
