Speaking of inside jokes...

Early last year,
Ice Breakers mints had a
TV commercial featuring various people exclaiming "Whoa!" upon experiencing their "Ice Cubes" gum, in response to one actress's mocking question, "'Whoa'? Who says 'whoa'?" The key to the gag was the final one, a cameo by
Joey Lawrence reprising his trademark "Whoa!" from the TV show "Blossom".
In what appears to be a slightly more subtle in-reference,
French's mustard now has a commercial featuring a voice that sounds exactly like
Didi Conn, saying "Food loves French's." Conn, you may recall, played
Frenchy in the movie version of "
Grease".
If that's not actually Didi Conn doing the voiceover, it sounds like a clever impersonation.
