Is it normal to want to stick my eye onto the wheel of a shopping cart?

I constantly feel an urge to bend down and place my eyeball onto the wheel of a shopping cart whenever I go to a store. it's very strange. It all started when my eyes were operated on, and then I suddenly felt an urge to stick the eyeball onto the shopping cart wheel. not the metal part, but the rubber, sort of hard part. It's driving me crazy, this urge, and I wish to know if any of you other fellows out there have tried it, or want to do it all the time. I usually do it on a daily basis, and as a result I visit the store quite often. This is a strange thing, this eyeball shopping cart mania, and if any of you could offer some quick cures I'd be very grateful. Thanks.
