For some reason I often think back to that one time during my #phd At a conference where I introduced my supervisor to pgfplots. He asked me why my plots in the conference presentation was not in pgfplots. I answered honestly, I had not had time. So the mother fu.... said well you have time now! So 1.5 hours before my presentation I changed it all to pgfplots.
He was laughing his ass of, that he got me to do it.... I should have seen the rouge.
