A husband is leaving on another business trip

The husband, being worried that his wife will cheat on him while he is gone, decides to buy an adult toy for her. The husband goes to a sex shop and sees the guy working behind the counter. The husband, not knowing what to get his wife asks the cashier straight up, "I'm worried about my wife cheating while I'm gone on my business trip, I need to buy something incredible to keep her satisfied while I'm gone." The cashier, without missing a beat, grabs a small pink box, already wrapped up, from below the counter. The husband asks what's in the box, to which the cashier tells him, it's the best toy money can buy, but he should give it to his wife and tell her not to open in until he is gone on the business trip. The husband agrees and right before he leaves for his trip, he leaves the unopened box on the bed for his wife.
Later that night, the husband calls the wife and asks if she likes her present. The wife hurridly responds, "oh yes, it's incredible, I'm actually using it right now." The husband is pleased with his purchase and they finish their call.
A few days later, the husband comes home from his business trip and finds his wife sweaty and out of breath. The husband asks what she's been up to and the wife, with a little smirk on her face, says that she was just using her new present before he came home. Being so impressed with the present, the husband goes back to the sex shop and speaks to the cashier saying, "My wife loves the toy I got from you and I've never seen her happier. I can't thank you enough for the present. You saved me from a lot of worrying. I must ask though, what was in the box?" To which the cashier hesitantly says, "my phone number."
