A note accompanying a stern looking gnome (who appears in several of the campaign's ads) reads: "If power is an aphrodisiac, don't turn your back on Vic at the lumberyard."
The implication to the text appears to be akin to the old homophobic saying among men, "Don't drop the soap in the showers" -- that Vic might attack another man from behind sexually. Or maybe it just means that Vic will steal the truck, but the double meaning seems intentionally open.
