When I was in high school one of my friends showed us this affiliate marketing site with some email function where you could send emails impersonating any email address you want. Pretty much the next day we used it to spoof his crush sending him some email hinting she liked him and he wouldn't stop bugging us whether it was real or whether we were spoofing. He went on about it for a whole semester. If only we got a bit creative. Also that friend was pretty a weird guy but he went onto go to Stanford and is now a co-founder for a large US tech company now which a lot of people here probably use. Yup. I'm gonna go back to my dead end job now
