I went on a date with a baker.

This little gem of a joke relies entirely on a classic comedy technique: the pun. The humor here springs from the delightful double meaning of the phrase "a piece of cake." On one hand, a baker, by trade, literally deals in cakes, pastries, and all things delicious, so a date with them might very well involve or revolve around actual pieces of cake. That's the literal, straightforward interpretation.

However, the real comedic frosting comes from the idiomatic use of "a piece of cake." This common English expression means something that is incredibly easy, simple, or straightforward to do. Dating, as many can attest, is often anything but a piece of cake. It's fraught with awkward silences, compatibility tests, and the general rollercoaster of human connection. So, the punchline cleverly suggests that this particular date, perhaps unexpectedly, went remarkably smoothly and without effort, contrasting with the usual dating struggles.

The joy of this joke lies in that unexpected twist, where the literal world of a baker deliciously blends with the figurative ease of a perfect date, leaving you with a light and sweet chuckle. It's a testament to how a simple phrase can hold layers of meaning, especially when buttered up with a bit of wit.
