Strange coincidence

If you licked something really cold, your tongue would stick to it. You see it in Dumb and Dumber (on the ski lift). Then again in Slap Her, She's French! when the little Geneviève licks the ice-ass of a cow. Of course there must be many who have watched these two films and remarked this little bit of coincidence. But why in the world should I watch them consecutively? This is a strange coincidence without any meaning in it...
