I'm an engineer too...and within 3 years, I will be a graduated engineer.
Next year I'll be working as an engineer for 3 days per week, and I WILL be an engineer, although I'm not graduated by then.
nah, it just made me remember of that joke, although i don't think you will get it. Juan (John) is name, and Juanito is like "Johnie", so......Juan-Nito
BTW, just found the name of that guy (the astronaut)......Rodolfo Neri Vela
