Czech *strč prst skrz krk* means 'stick your finger through your throat', while *vlk zmrzl, zhltl hrst zrn* just indicates that the 'wolf has frozen, gulped a handful of grains'. Slovak - Czech's closest sibling and full-fledged partner in terms of consonant clustering - has stopped short of having the wolf freeze or swallow to utter vowellessness: *vlk zmrz**o**l*, *zhlt**o**l* is how the latter would put it!
