Sounds like your bar diameter is too small. I've put on Ourys with hairspray, and track grips with WD40 and they take quite a bit of muscle to remove.
If that were the case, I'd first try wrapping the grip part of the bars with electrical tape or something to increase thickness, then shoving the grips on. I dunno, he might die though.
