present and repent
If you've ever worked in an agency then you've been guilty of this as least one time in your career --> the over-promise in a pitch.
Maybe you said you've done something you never really did. Or you can do something you're pretty sure is impossible. Or in the case of this video created by Balmer Partnership, committed your Sr. level staff's time with no real intentions of actually doing so.
As AdPulp points out, it's reminiscent of the hilarious Truth in Advertising ad from years ago which was done way better than this one - but it still will get a little smirk out of you.
