Ugh I have a mosquito related tale of woe as well. In 2003 I was working in Canada for a little while, and took my mtb out there so I could get some exercise and make friends easily at the local mtb club. The mozzies out there (or skeeters, as the canadians call them) are an order of magnitude larger than anything we have in this country. Anyway, for one evening ride out in the local woods, I dutifully covered myself in mozzie repellant and set off - or so I thought. I'd sprayed every part of myself - clothes and all - except my arse, as it turned out. So, imagine the scene, riding through woods, arse in the air, every mosquito in the area homed in on it and went in for a munch. I felt the odd sting, but nothing much, until I woke up the next morning to find that my entire arse swollen with about 40 gigantic mosquito bites. Baboons eat your heart out. It was three days before I could sit down properly. I had to take strong oral antihystermines to sort it, and bore the scars for several months. Oh boy. In the words of Morrisey, I can laugh about it now, but at the time it was terrible.
