Occasionally Irene will have a bad gas day or spend a little too much time daydreaming about smooching and hugging Sally, which can cause her to go airborne much earlier in the day than usual.

Irene’s condition is very much an open secret at the lab, and thankfully nobody really makes that big a deal of it.
