Not companies, but when I was at school, the woodwork master was called Mr Glue, and one chemistry teacher was Dr Spillet!
Alike these, we used to nickname each and every teacher in our school. Ours was a "Only Boys" high school and we used to name these teachers as follows:
Chemistry sir --> Likud becoz he was from Madras and he used to pronounce "Liquid" as LIKUD.
Biology sir --> Arthropoda (The organism "Arthropoda" was his favorite !
Hindi teacher --> Rambo (One day she got hurt on her forehead and she came to school with a huge ribbon wrapped around her forehead) !
Sanskrit sir --> Ravan ( In hindu mythology -Ravan is supposed to be a beast and he was given this name cuz of his beastility acts) !
History sir --> Sattu (Sattu represents a "mavaali" name. Mavaali - meaning road side romeos)
Geography teacher --> Haafus (Haafus is a hindi word for mango - and just because her breasts were the shape of a mango and her real name was Alphonso,
)
Physics teacher --> All the bad words which you can think of in Hindi or English..hehehe !
English teacher --> Sir Joy (Actually the teacher is a female and her real name is Joyamma but she portrayed an actual male in her and hence we named her "Sir Joy" !
Algebra sir --> Bagla (Bagla is hindi word for a duck
he used to walk like a duck in school hence this name)
I dont remember but a hell of names we had in our school days. Oh boy, these were my wonderful days where we enjoyed each and every moment of life. So sad we can never have them back
