Pulling a mycroft 

When you forget to turn off the stove, when making tea, after a number of hours, your water has evaporated, and your pot is seared; consequently also, when you forget to turn the stove on and you wonder, after a lengthy period, why the water isn't the least bit hot. *Can be used in reference to any kitchen dealings.

"Jenny, the water evaporated, you pulled a Mycroft again!" - "Silly water won't boil if I pull a Mycroft."
