S2·E9 Grease Monkeys in Space

The Man With the Yellow Hat is about to get a big job! He is going to go up into space to fix the Einstein-Pizza Space Telescope, which is broken and pointed right at Pizza's kitchen window. Dr. Einstein and Professor Pizza explain that the spaceship has a self-locking air lock but they accidentally forgot to make a way to open it from outside. George has to tag along to push the button that would let him in but is forced to go outside and do the job when the Man's tether breaks. Worse off, George is told he has only 2 minutes of air to complete the job.
