I was telling Garrett the other day about an television ad from a few years back where there's a guy interviewing for a position at a high-powered firm of some sort, and he repeatedly mispronounces the firm's name to hilarious effect. Garrett didn't think it could be real, but I found it on youtube!
I have obscured the punchline in my description, but the ad is mostly worksafe - the language is just this side of swearing.
