Plastic cup Puns

My answer is always the same: Because.

"Hey, barkeep!" he says, struggling to keep control of his quarry. "Any room for me and my friends?"

The bartender smiles and sets down some plastic cups. The man plops his friends inside, but the cups are too small.

"Um...barkeep?" the man says, pulling them out again. The bartender reaches for some larger mugs, but as he places them next to the cups, it becomes obvious that even these will be too small for the pigs.

Seeing the man struggle to continue holding them, the bartender runs to the kitchen for help.

A cook emerges, holding several large measuring cups. "Sorry, I just used these to make a batch of cheese dip, but they're all yours!"

The man carefully plops each pig into its respective gooey yellow cup.

Arms exhausted, breathing heavily, he drops into a stool at the end of the bar, between his tiny friends and a beautiful girl.

He glances her way, gasping coyly. "Hey...I'm...Tom."

She smiles, having watched the whole ordeal. "Hi Tom, I'm Liz. And if you don't mind me asking..." she laughs, looking over his shoulder, "what was that all about?"

He glances back at the bar. "Yeah...sorry," he pants. "I wanted...to impress you, but...it turned out to be...a pretty cheesy...pig-cup line."
