Big & Fresh has teamed up with comedian Dom Joly to raise a smile in the egg aisle.

Its large Class A eggs are to have egg-based jokes written by Joly printed on their shells - with the punchline becoming visible once the egg has been flipped.

Big & Fresh is adding ‘cracking yolks’ to its eggs on a trial basis only, but will consider a commercial rollout around key seasonal times of the year.
