Oh boy.. An egg...
Amateur hour on the stink front. To really ramp up the odours, I'd point you in the direction of the far east (with eyes watering whilst holding my nose) and to the 'King of Fruits' (allegedly), the Durian.
They're banned from public transport and even from hold luggage on flights, such is the maloderous stench this fruit is blessed with. It's pretty much what you'd expect a 7 day old corpse to smell like, left in the jungles of Malaysia.
They should (and do) come with fines for eating near other unwilling and unwitting passengers.
