Blame Eric Short Sleeve
Scissor-lift breakdown at full extension because you were messing with the controls? Van interior covered in red aerosol paint after you left the cap off? Amp blown? Accidentally contaminate the local water supply after you spilled a full bucket of emulsion? Expensive projector lens cracked? Compressor air-line blocked because you didn't read the manual? Charger cable lost?
