My girlfriend was reading some medical information, and she got to a part that was like "128 mg dose of blah blah" and she pronounced "mg" as "meg". I said "No, 'meg' would be short for 'megagram' and that would be a huge-ass pill! If you said you had 256 megs of RAM in your computer that'd be okay, short for megabytes."
"Nyuh uh, that's how doctors say it!" -her (not a doctor)
