There are only a 100 or so Tastee Freez stores in the US (and Panama!), but the new owners control a hot-dog chain with 350 outlets, and plan to combine tne brands. Wikipedia says:

"In the 1950s, Tastee-Freez had the Tastee-Freez Twins mascots: Tee (female) and Eff (male). The mascots were naked with ice cream (strawberry and chocolate respectively) on their heads." Naked, yes, but not what you'd think.
