Do you have a desktop computer? If so, and you know where the power supply is, you could touch the metal grate on that. The power supply will be earthed due to requiring a ground, and the cage itself is properly made so maintenance can be done safely by connecting an ESD wrist strap to the power supply cage.
If you don't feel or hear a shock, you have not discharged.
If you have more patience, you can wash your hands for 2 minutes and you wouldn't be statically charged. Though, that may be really cold as an after affect.
