When you think about the life of a professional athlete, you probably imagine Valentine's Day spent with a loved one on a trip to Napa Valley or a helicopter ride in Hawaii. And while that is likely happening this Feb. 14, there are just as many MLB players celebrating with heart-shaped donuts, dinner at Cracker Barrel or a card hidden in luggage before they leave for spring training.

Oakland Athletics reliever Sean Doolittle and fiancée Eireann Dolan don't craft any lavish plans at this time of year because the pair has already established a more casual tradition for the holiday: Taco Bell.

Dolan orders double-decker tacos -- beans, no meat (she's a vegetarian) -- and he orders, well ... "Everything," she said.

If they decide to really get crazy, she said, they might end up doing a puzzle too.

The relaxed celebration necessitated by the crazy schedule of a baseball player doesn't bother Dolan at all, but Doolittle got in a romantic gesture before the offseason ended.

An unabashed Star Wars nerd, Doolittle dressed the couple's dog, a Rhodesian Ridgeback named Stella, as Princess Leia and stationed her next to an R2-D2 replica doll to lure Dolan into a room filled with candles, where he presented her with the bauble and uttered, "Marry me, Eireann. You're my only hope."

Of course, Dolan, who has indulged Doolittle's Star Wars obsession, understood the reference.

"He's really into it, and I tolerate it. That's what relationships are: compromising and tolerating their obsessions," Dolan gamely joked.

A keen sense of humor has always been the cornerstone of the pair's relationship, and it was instrumental in what brought them together in the first place.

The two were introduced virtually, over Twitter, by Doolittle's former teammate, Los Angeles Dodgers pitcher Brandon McCarthy. McCarthy and Dolan were collaborating on a comedy writing project in L.A. at the time, and he thought the two would be a great match. After McCarthy told Dolan he had a teammate he wanted her to meet who was "super funny, super nerdy," Dolan asked his name.

Her response?

"That sounds fake," Dolan recalled in a phone conversation with ESPN.com, laughing about the fact that she later Googled Doolittle to ensure it wasn't a ruse.

The two traded texts and interacted occasionally on Twitter after that. Then McCarthy made another bid to link the pair when, in a 2013 interview with ESPN The Magazine, he named Doolittle and Dolan the two funniest people he followed on Twitter.
