This year brought the happy coincidence of Easter Sunday falling on April 1^st, or April Fool’s Day. So instead of your work colleagues or classmates falling victim to your fiendishly ingenious pranks, it was family and significant others’ that were the target this time.

Glasgow-based Welshman Chris Erwood got into the spirit of both occasions by presenting his girlfriend Alicia with a perfectly disguised prank-egg. With an impressively well thought-out and well executed effort, Chris shows us how, with a handy step-by-step guide, to construct the egg for “the arachnophobic in your life.”

Now if Alicia really is an arachnophobe, then this prank is pure evil. By the look on her face, it was certainly effective, and we are pretty sure Chris has some mad trouble headed his way. “I am expecting some sort of revenge,” he said after the incident. And quite rightly so! Scroll down to check out how it all unfolded and let us know what you think in the comments!

This is Chris Erwood, and you might not assume just from looking at him, but he’s a master prankster

And this is his girlfriend Alicia, who had no idea what Chris had in store for her this Easter

“I bought this egg already in two halves, but you could just cut one open with a hot knife”

“Add chocolates. It reduces the number of spiders you need and it’s a consolation prize”

“Oh look, my bag of 200 plastic spiders arrived!”

“Perfect for the arachnophobic in your life”

“All in all, that’s about 100-120 plastic spiders”

“You’ll need to melt some chocolate to stick the halves together”

“Done! Once this has cooled you can use a sharp knife to shave down the excess”

“Carefully wrapping it in the foil from a donor egg”

“The perfect disguise”

“It worked”

“This photo may one day be evidence in a murder trial when she kills me”

“Happy Easter!”
