Crash in Heathrow

I landed only once in Heathrow, but others experiences with this airport must have been really bad to trigger such jokes after the crash in Heathrow:

On a practical note, relieved passenger Mr Miles O'Flyte said:
"After we landed, as the undercarriage had been crushed and the hold doors had popped clean off their hinges, I was able to simply pick my bag out of the wreckage and carry on through customs. Not only was it the fastest I've ever cleared Heathrow on arrival, my luggage was also less damaged than usual."
