Premise: yeah we had a rabbit up until uh last summer and we gave him away because the girls lost interest in him and couple of them we're getting allergic to rabbits uh i uh we had a tough time deciding on a name so i named him uh Mister Tibbar and they wanted to know how i figured out that name and i said well it's rabbit spelled backwards

Hypothesis: We've never owned a rabbit. 
Relation: contradiction
