Trust me on this - wear more than your boxers and get a shower after ...
Beats getting one at three in the morning cos you cant sleep, I felt like a cactus
Didnt end there either, even after the wash that pair of boxes bugged the shit out off me all day at Alton Towers, only when I got home did I make the connection
Second time was outside - kept hosing the area down and all my stuff went straight in the washer
