My favorite silly IFS unit is the "second" of Isp, defined as the amount of power a rocket produces (force in pounds integrated over the burn time period) divided by the weight in pounds of fuel consumed. To call this a "second" is to conflate pounds-force with pounds-mass. I believe the unit translates as one "second" = 9.8 N sec / kg.
