Nothing says ‘I love you’ like the gift of crabs. No, that that sort. Instead of taking a trip to the local STI clinic, why not head to the Sea Life London Aquarium this weekend where there’s a crustacean invasion taking place. Their new ‘Claws’ exhibit lets you get up close and personal with the little snappers and anyone with the surname Crab (or Crabb) gets in free this weekend (Feb 15-16). All the crabs, none of the itching. Perfect.
