a conversation between some chemical engineering grad students:

che1: he's a good mood today...an unusually good mood
che2: we must have won at basketball
che1: he hates his wife
all: ...
che1: he has a toothbrush in his office. he hates his wife
che3: all these chemical engineers hate their wives
che4 (female): i'm a chemical engineer, and i don't have a wife. i have a husband, and i like him just fine
che1: just wait until you get a career
