So anyone want to admit to trips to A&E / ER or calls to the emergency services?
Since April 2013 the capital's fire crews have:
Attended 28 incidents involving people being trapped in handcuffs
Removed 293 rings, including seven from male genitalia
Attended other incidents, including releasing men's genitals from toasters or vacuum cleaners
On another occasion, the brigade was called by a woman whose husband had become locked in a chastity belt.
A spokesman added that while there could sometimes be a "funny side" to some of these predicaments, they could be painful and "end up wasting emergency service time".
He added: "Our advice is to try and avoid getting in that position in the first place."
