Tip of the tongue Puns

The words are right on the tip of my tongue.

It was on the tip of my tongue, but Affogato.

I couldn't explain because it was on the tip of my tongue.

Give me a second; it's on the tip of my tongue.

Oh heck what's the name of it? it's on the tip of my tongue...

When they arrived, a cab driver greeted them at the airport. "What should we do on our first day here," the father asked his son, excitedly. The driver interjected, "Well, if you're not natives, I'd suggest the roller coaster that teaches your or language." Confused, the father and son look at one another then back at their guide. "Trust me," he told them, "It's guaranteed or your money back." Having no plans and now both understandably intrigued, the pair agreed. When they arrived at the roller coaster, they were amazed to behold the giant steel skeleton of the most intricate ride they'd ever seen. It had loops, helixes, corkscrews and drops more terrifying than anything they'd ridden back home. The son quickly rescinded his consent and turned you guys father. "There's no way I'm getting on that thing. You go first," he said, "Then you can tell me if it's worth it." Not wanting to seem a coward, the father accepted. Stepping into the first car, he seated himself. As the attendant approached to check his shoulder restraint, her couldn't help but ask, "So how exactly am I supposed to learn an entire language from a roller coaster?" The attendant smiled and replied simply, "You'll see." Anticipation turned to unease as the cars lurched upward towards the first drop. The seconds felt like hours as the car climbed higher and higher, clicking steadily while the chain pulled it skyward. As the nose of the car tipped downward and he could see the enormous drop below, his inner fear turned verbal. Without thinking he screamed, "minä kuolen!" As he rounded the first turn and into an inverted twist, he debut another exclamation well inside and burst forth. "naida!" He screamed as the ride continued. A few minutes and many foreign-tongued exclamations later, he found himself back at the station trying to catch his breath with the smiling attendant removing his restraints. His ran up to his son and declared, "It really works! I'm not sure how, but it really works!" "How was it?" the son asked unimpressed. "It was a wild ride from start to Finnish." "The son smiled weakly. "Yeah , the cabbie stole our luggage."

Him: "Ask what's-his-name to do it."

Me: "Who?"

Him: "Argh, his name is on the tip of my tongue."

Me (leaning in, looking at his mouth): "I don't see anything."
