Wife called her scientist husband. Honey.. Its Saturday.. ur late...
Husband - Darling, I'm busy with my team in an experiment.
Wife - What's that?
Husband - We added a derivative of C2H5OH�with H2O at ambient temperature and aqueous CO2. Then we added some super low temperature, solidified H2O and now, while waiting for some protein, we are fumigating the lab with nicotine vapors. It's 4 or 5 round experiment. So I will be late.
Wife- Oh dear, you're really busy! I won't disturb you. Take ur time.
