Are you feeling a little dazed, silly, or light-headed? Are you talking incoherently as if you've received repeated blows to the head? Would you perhaps describe yourself as punch-drunk? Happy-go-lucky? Have you recently been sleep deprived or are experiencing excessive feelings of fatigue or tiredness? Have you become prone to inane semi-maniacal rambling? Have you been making strange and/or meaningless remarks? Are you demonstrating fits of random and inexplicable behavior? Did you just give yourself a wedgie? Experiencing bouts of uncontrollable laughter -- at your own jokes? Standing on a silver surfboard holding a hot dog and wondering why?!
You're off your rocker, dude; Slaphappy!
