Thats pretty wild!
We caught a 20lb FH catfish on the Missouri river one day that had taken our bait, which consisted of about a 1 lb bullhead catfish on a bank pole, and mostly swallowed it headfirst but just got it down far enough toe where the barbs on the BH I guess wouldnt let it regurgitate it, when we got the FH into the boat we pulled the hook right out of the BH with very little effort, the FH never had a hook in him at all.
