Nope! It's actually terribly innocent. 'stick' in this context just means trouble in a joking way. Some friends probably took the piss out of him/gave him grief for being so stupid - as he worked at the jet propulsion lab he should have known better.

I've just realised while writing this how hard it is to explain 'stick' without resorting to even more Brit slang. So if none of that makes any sense, apologies in advance! At least it'll give all those US'ns another opportunity to say how odd our English is ;-)
