Do not use your teeth to try and open the crazy glue tube.
There could be a miniscule hole SOMEWHERE on the tube which could result in crazy glue being shot over your tongue and the back of your teeth.
Do not use a paper towel to frantically try and wipe it off before it dries.
Resist the urge to get a knife - even if you think it's dull - to try and scrape the glue and paper towel off.
The dried glue residue mixed with the cut on your tongue probably is not pleasant.
