This one is for all you cellphone yappers...
How to cook a (rather modest) dinner while you are on the phone? Easy, just make sure you and your roomate /friend /innocent-bystander /random-intruder-in-your-apartment / officemate have your cellphones charged.
A couple of other stuff you will need are - an egg, something to hold it in place, a hifi - and you are all set.
cellphone a --> egg <-- cellphone b
"Note: We cooked our egg during the evening using free local calls, if you were to cook an egg for lunch it would cost £3.00 - not cheap but you do have the convenience."
