There was a pajeet who'd sometimes sub in for some of my lecturers at uni, and he was like a personal lolcow for the whole department. There were a couple of jeet PhD students who took our undergrad tutorials and seemed pretty normal so they weren't all bad, though the Russians, Germans, Americans and east Asians were better obviously, this was maths. He was from the Punjab, had moved to Sunderland, and was half deaf, so he had the thickest, most incomprehensible accent imaginable. One time he took out geometry class and filled up the board with scrawls, then asked the lecture theatre "...what happens now?"
"Uh, usually she gives us a five minute break while she cleans the board."
"WHAT!! FINE, I'll give yez a brek while I clean the boards."
He started scrubbing at it and realised he'd used permanent marker, and bellowed "OH SHIT!!" into the microphone. His solution was to scratch off his name and write our usual lecturer's name at the top to blame her instead, and he said "yez can aal gan hem now" and finished the lecture early.
My buddy in the Discrete Maths class that sometimes had him looked him up and discovered an article that said he (or a guy with the same name) faked his own death as part of an insurance scam and fled India and bigamously married some lady and entered the UK on a dodgy passport. No idea if it was the same guy, but ever since, we'd hum "You Only Live Twice" every time he came into the lecture theatre. I think he's still in charge of the admin at the maths department, the timetables and homework submission systems were always a Byzantine mess and people would complain about it on Facebook and student websites and the like.
