What I like to do at home is pour them into a paper cup. That allows me to funnel them into my mouth so I can get a whole bunch of them at once. I wouldn't do that in a restaurant however.
Eating corn is difficult as well. Especially corn on a cob. Unless you are at a backyard barbeque, stay away from corn on the cob at the dinner table. Not only will you gross people out but you will get the corn stuck between your teeth and then you have to decide whether or not you are going to free it with your fingernail or hunt down a toothpick. Either option will not sit well with your spouse and could earn you a divorce.
Watermelons are worse. There has never been a socially acceptable way to eat them.
