What’s the most money/time/resources you’ve ever put into a gag gift?

My girlfriend took to answering "your right nipple" as an answer to anything she felt was a dumb question. This developed into something of a dumb inside joke that neither one of us really remember the origins of, but I took a photo of my right nipple and commissioned an artist to recreate it in oil (cost me about $250 excluding the fancy frame) and had it delivered to her house

She had also always wanted a pogo stick since she was a kid and saw them in TV shows and would often talk about them. Like, not just once but over the past two years she'd mention her pogo stick dream dozens of times, so for Valentines day I tried research which pogo carry adult weight and various review sites and got her a $480 vurtetgo V4 pogo stick with a note inquiring about whether or not it was suitably phallic for the occasion
