Maybe Gumby could have a "work commitment": writing a book entitled
"Gumbocratic Warfare: Love-Bomb Evasive Tactics",
using, of course, the many creative suggestions on this thread. Complete with illustrations. I'd buy a copy.
To add some more:
1. Green veggies stuck in the teeth are a turn-off. (I recommend broccoli or spinach)
2. Leaning a little too close (invading the other's personal space) when talking. He needs to be sure to use this equally with women AND with men, so as not to be accused of inappropriate conduct towards the other sex.
Of course, one has to wonder, how would his wife and kids feel about all these manouvers....
