find a design you really like and get it made in neon...
that or a big MJ leaf. a good neon sign maker im sur ecould make something really neat.
or a big bottle of duff beer in neon
i just like the cartoony look to them.
or maybe a naked woman in neon, or just a giant set of tits.
or a sign that says loser, and when you lose a game of pool you have to sit under it and wiat your next turn.
or a sign that says beer, with moviing arrows pointing down, and you could hang it above your mini-fridge. or your keg cooler
