I've not had my tonsils out, but my brother did at the age of... six, I think, so in about 1989, and I am pretty sure jelly and ice-cream featured. (He had his out after several ENT issues, and apparently that solved them.)

I had a double tooth extraction a few years back (one wisdom plus the molar in front of it) and was advised to 'be careful' and 'eat/drink on the other side'. Which, considering my mouth was still going numb for a hour or two after said extraction, thanks to a double shot of anaesthetic, was fun to attempt.
